Ok just for the safe way, copy your Roblox folder. Now, delete your roblox folder that is the old one. Finally, click the "Download now" button when you try to join a game. Then it will create a new Roblox folder and you will hopefully be able to play ROBLOX again :). If this doesnt work you can just paste back your roblox folder right where you found it.
ROBLOX File Location:
C:\Users\Name\AppData\Local\Roblox\Versions
Change "Name" with your username for your computer.
This problem occured to me and I fixed it like this.
Hope I could help :)
