Which DLL error box is still appearing?

Restore points... maybe your hard drive is filling up? Restore points take a lot of disk space... however I would think if space began to fill up it would delete older ones as needed, not wipe out all of them in one fell swoop.

I don't use the restore points here, (I just keep careful track of everything and backup manually) so I can't say exactly how they are designed to add/delete.

Don't forget though that this could also be a registry issue... as I described above, the restore points involve making backup files on your hard drive, including the data of all the settings at that point in time... but the information that you have restore points... the list of restore points and the dates and such, are all stored, you guessed it, in the registry.

So if something deleted the list from the registry... the disc space and all the actual info needed for those restore points would still be there, but the dialog box that comes up that shows you the restore points would no longer have any "memory" to give you the list of those restore points.
