title says it all. and don't suggest going on the launcher, because if that's all it took i wouldn't have posted. Every time i try to log in it gives me login failed, no matter how many times I try or if get it right or not. It's not in the recycle bin, I deleted the folder because it was ruined by a mod pack I downloaded. I do have backups, but I have no Idea how to make the backup work. sorry if the fix is blatantly obvious, I'm new to this sort of thing.
u can rename your .minecraft folder then then force update then put your precious files in the new .minecraft and press yes when it says
merge hope this helps
btw and do i change a file i renamed to the .minecraft?
