I just installed Firefox 4.1, decided it was bullshit, tried re-installing 3.5, now whenever I try and open a new tab this bullshit happens.
"firefox.exe - Entry Point Not Found
The procedure entry point_except_handler4_common could not be located in the dynamic link library msvcrt.dll."

It's been happening with my MSN and Photoshop, too, but this is the last fuckin' straw, over this shit.
I'm running on Windows XP, if that matters.
I need someone to explain to me what the fuck to do, in words I can understand; I'm not exeptionally tech savy.
