I do not know what Jason's Toolbar Script Sentry (SS) is supposed to do or did, perhaps the following will give you some ideas to check.
Description of the Microsoft Windows Registry (Q256986) - all MS operating system versions
1. The Registry Editor is an advanced tool for viewing and changing settings in the system registry. Windows stores configuration information in a database (the registry) organized in a tree format. Although the Registry Editor enables inspection and modifying, it is normally not necessary.
Note: The two most important things to know are that the system registry copies changes immediately and there is no Undo command. The editor does not wait for a Save to be issued since it does not have one, therefore making changes permanent as they happen -- you make a change it's gone forever unless you remember it or have already backed up a copy. Use the editor sparingly and soberly, and do not leave it open unnecessarily.
2. The article [Q318159] explains that when a registry hive becomes damaged, your computer may become unbootable, and you may receive one of the following Stop error messages on a blue screen. Damage often occurs when programs with access to the registry do not cleanly remove temporary items that they store in the registry. This problem may also be caused if a program is terminated or experiences a user-mode fault -- one created by the user:
Unexpected Shutdown
Stop:0xc0000135
3. The article [Q307545] describes how to recover a Windows XP system that does not start because of corruption in the registry and assumes that normal recovery methods have failed and access to the system is not available except by using Recovery Console. If an Automatic System Recovery (ASR) backup exists, it is the preferred method for recovery and it is recommended that you use the ASR backup before utilizing this procedure. This procedure does not guarantee full recovery of the system to a previous state; however, you should be able to recover data when used.
4. Please note that on occasion it may be come necessary to utilize the older Regedit32, run the same as Regedit, when access issues a denial permissions.
5. Supplemental reading:
a. "Prevent Regedit.exe from Using the Last State (Q244004)."
b. "The Registry Keys and Values for the System Restore Utility (Q295659)" describes certain keys pertaining to System Restore which must not be edited under any circumstances.
c. "HOW TO: Back Up, Edit, and Restore the Registry in Windows XP (Q322756)."
6. Five "Administrative Templates ship with Windows XP SP1" which includes more than 600 settings with over 100 new settings, and must be manually configured in the Computer Configuration in the Group Policy Object Editor to apply them.
7. The Prevent access to registry editing tools setting disables the Windows registry editors Regedit.exe and Regedit32.exe. Enabling this setting causes a message to appear when the user tries to start a registry editor, informing him or her that s/he cannot use them. This setting prevents users or intruders from accessing the registry using these tools, but does not prevent access to the registry itself.

For some reason, Jason's Toolbar Script Sentry (SS) is not working http://reviews.cnet.com/5208-6142-0.html?forumID=45&threadID=25992&start=0
Messages at his forum are unanswered http://www.jasons-toolbox.com/Forum/topic.asp?TOPIC_ID=278 so far.
I tried uninstalling SS, but it is still there (?????)
Now when I try to open a REG file (merge) I get the "no association dialog). If I try to associated it with SS (yup, it is still here even though I ran the uninstaller and deselected it from MSCONFIG/ startup) I still get the error message. (error 53)
What other application do you associate the REG file if you want to merge it.
As to the file I trying to merge, it is Spyware Block List files (yues, there are other things I can do to immunize, but I am more interested in having the computer work correctly)
any ideas?
