Minecraft Forums

I need some help. I am running on a 64-bit Windows 7 PC. Just two days ago minecraft ran perfectly fine, no issues at all. But now I try to log into the game and the window just closes. Like I open the file log in then it loads all of the files, the window goes black for about two seconds, and finally the program just closes. I don't even have to click anything for this to happen. I have tried deleting and recreating the bin file, deleting .minecraft file, and even re installing the program itself all with the same results. Not even a crash report appears in the .minecraft file. Any help would be appreciated, thanks.
