I don't believe they were deleted when I upgraded, but I believe some kind of virus detector went ahead and deleted the files, as I've had this happen before. Remember at first I opened the folder, and was able to click the .exe---its only after it didnt work that it was missing after. Now there's no trace of the working .exe, even if I use file recovery. Today, when I try to start the ame, I get a new message---- "This app cant run on your PC" To find a version for your PC, check the software publisher. FML
Okay so I pretty much confirmed it was "Windows Defender", which I shut off before but got turned back on automatically with Windows 10. Windows Defender aggressively tries to eliminate 2K sports files. I went into the quarentine thing, and found nothing but NBA and MLB 2K files. I tried to restore them all back----but my .exe still doesn't work, it says it cant be found even though its right there. FML
