I'm not really sure what would be causing this. If you know how to runs mods using the vanilla launcher, I would suggest trying that. Also you could force crash minecraft using F3+C (you may have to hold it for a few seconds) while in game to generate a crash report, though I doubt I will find any useful information in it.

I assume you've already restarted your client, correct?
