Minecraft Forums

A couple weeks ago I downloaded an X-ray mod, and it worked perfectly for a few days, but then minecraft started crashing every time I opened it. Frustrated, I deleted every Minecraft file on my computer and decided to play vanilla from then on. I downloaded the game again, and it's been working fine until today. Now, once again, it crashes every time I open it. I've tried force updates, and uninstalling, then reinstalling but it's not working. What do I do? Here's the error report:

I'd like some advice as fast as possible please, so I can start playing again ASAP. Thanks!

Thanks for the advice guys, I'll work on it and update you guys when I get the chance.

I forgot about some tinkering I did with some of my computer's data, and it turns out that all I needed was a system restore. However, I think that I should probably update my Java...
