Okay wow, the thing just magically started working today..!

(shoot, sorry for the @)

MGI has stopped working for me all of a sudden too, It was working perfectly fine until I added my third acc, which I usually do, and then it just completely stopped working, saying "Shutting down Roblox", closing the account that was open, and "Updating roblox" everytime I tried doing it again. I turned off my antivirus/firewall, restarted the computer, reinstalled, logged out and logged back in on roblox, and downloaded the other version. Is there anything else I can do?
