Another thing, just so you guys (Bryce and mccann98) know. Winrar is effectively free. It has a forty day trial after which a window will pop up that looks like this. But all you have to do is click close, and the program will continue running fully functional for free.
Here’s an article that explains why this is.
Also, do you guys know how to verify a file’s checksum? It’s a fairly quick way to check if a particular rar might be corrupted, and especially if you think a particular file might be causing the problem. Let me know if you would like to know how to do that, and I can help you run those tests if you like.
