I reverted back to a last known working config, from the safe mode menu, after I got malware that I couldn't get rid of. It was a good one. Power loss and everything.
Now, my user profile, we'll call 'Ray', has errors when trying to access anything from mIRC, to Firefox, PaintBrush, SpyBot, Adobe, etc... and anything in between. I get the pop-up that looks like this(I can't screenshot on that profile, sorry):
The pathnames in the title look correct. I can't access regedit, I can't access system from the Control Panel. I've checked google for 2 days now and I have found nothing helpful, other than "Does that profile have admin permissions?" and the answer is yes. From profile Admin, I can see that Ray has admin permissions. I've had people suggest environmental variables, registry changes in the CDM key (which I don't have in local_machines for some reason).
Sorry I can't follow most the rules with pasting logs from the programs you've requested. They won't work on that profile. I am running Windows XP SP2 on an HP laptop.
As a side note, my scrolling on the touchpad no longer works on that profile either. Minor in comparison. I'm sure I can fix that later.
I'm a stay at home dad, so should be able to respond pretty quickly, as I will do the same thing I did yesterday; sit at the PC and Google the same question 100 different ways!
