I was trying to mod minecraft today (unsuccessfully), and tried reinstalling minecraft to get a 'fresh' minecraft again. I copied/pasted my worlds over, and loaded one, but it stuck on the loading screen with the program (Not Responding), followed by a crash. I tried to create a new world, only to get another (not responding) with another crash. I can't load any world without the game crashing. Help!!
The problem may be fixed! I just detected some adware/shovelware that probably came with some mods I downloaded. I promptly uninstalled them and scanned my pc. Everything seems to be working now, I'll repost if there are any more problems.
