this has not been resolved; my game still crashes every time i try to open it, and how am i supposed to try using a different texture pack if i can't get into the options to change it? I tried deleting the resource packs and i'm still getting the same error, and i've never had this problem before when using these packs.

ok so i deleted the .minecraft folder and reinstalled minecraft and it worked for a couple of days but now it's crashing again and this time there are no resource packs installed at all.
