Adam, I was getting the blue screen with any size file, even blank ones that I had saved while the SR3 patch was applied. I've been having other problems as well and finally a friend commented that it sounded as if I had a boot sector virus. Well, my anti-virus program has always come up clear on those, so I found a little freeware program and guess what? I had a boot sector virus. After cleaning it, I reloaded the SR3 patch and so far, I can save and open files with no problem, however, the files I saved before, I still can't open (get the blue screen), but those I can recreate. I never had the SR1 or SR2 patch since I just got the Pro Pack, so I have no idea what the differences were or how they would work on my system. I sure hope you figure out what is happening soon.
