I'm curious as to what in the registry changes when you run safedisc4hide because I can no longer run Diablo II and I'm almost positive that this is what did it. I built a new rig about 10 days ago and install D2 from the install files downloadable at the Blizzard website. It ran fine when I did a test run. Fast forward to tonight, when I felt like playing, and now I'm getting an error from Bnet saying it can't properly identify my version, even though I just did a fresh install using their installer again. I realize this sounds like it might belong in the gaming forum but my problem I feel is related to sd4hide, NOT D2. Some buddies and I were planning on playing and I've gotta figure out how to fix this problem (which I'm assuming is with the registry) before that can happen so any help is appreciated.
