with the network share anyway. As for the "permissions" issue, you'll need to determine if the problem is with the share or with your recently "tweaked" PC. Can you access this share via another PC (if you have one)? I'd also try logging into the PC using the Administrator account...not just an administrator account. When accessing the share, you might then be greeted with a username/password box to validate yourself. You'd need to enter a proper username/password that's defined on the device where the share resides. One step at a time....see if that works.
It's also advised to be wary of these 3rd party tools. They often mess up more than they fix.
