I went from beta 4 to beta 5. I'm always playing with the system so i don't miss anything. On a good note I'm on beta 5 now and everything is working. After reverting to beta 3, when i opened bigbox it went straight into the installer and made me install the newest version. I'm not sure what the problem was really. I'm on windows 10 with the new creators update. I deleted all the C++ and reinstalled. That said it was still crashing after I did that. It wasn't till I reverted to beta 3 and bigbox installed the newest version. Maybe just a glitch in the initial update that just needed to be reinstalled on my end.
