Don't use Regcure. If your registry is a mess, this could only make it worse. Most likely, however, it's not a registry problem at all.
Likely causes for such a message:
1. Problems with the mail server at your mail provider. The easy diagnostic: try on another PC or laptop. Or just wait half a day and try again.
2. Your firewall or antivirus interfering. Usually someone overprotected his machine and then this happens.
3. Using registry cleaners. Those are the most difficult to solve.
I am currently running WinXPPro, PIV-1.6. 90GHD, IGRam. I use Firefox exclusively. I have been getting the message OX8000cccof and the mail server times out.
I am also using PC Tools "reg mechanic", after running "reg mech' three times, I get the message that my machine is "clean".
Still having the problem, I ran "reg cure" and it says it found 21 problems and it will fix them all for @29.95.
Any ideas, suggestions, fixes? Thanks, Bill
