I was playing with MOD installed on 1, 6, 4, but suddenly from yesterday it started to display "Sorry, but Minecraft cannot be started." The same symptoms occur even after reinstalling the launcher and driver. After reinstalling the launcher, vanilla 1.6.4 starts only once, but after that it won't start again.

I am writing this in the hope that the symptoms will improve and I will be able to play again. thank you.
