hermesdr1, I had that problem a lot of times. Thank God that I fixed the problem. Here's the solution.
Redownload it. Just redownload it. It's damaged? Just redownload.
Also..don't extract it into the Pintos folder. Extract it into the desktop. Why? You'll get the same problem over and over again. (That happened to me.)
After you're done extracting, highlight all the folders u received and place it down into the official Pintos Online folder. It'll tell you if u want to replace them. Say "yes" to all. After that ur done!
Also if u get a game guard error..just msg me or something. I know how to fix that.
Hope that helps!
