Anyone else freeze and crash at login screen?

Whenever I open the SL program, it'll freeze and crash before even reaching the login screen. I crashed about 3 days ago while in-world and went back to login and have had this problem ever since. No new hardware, same stuff I've been using that's been working perfectly fine for the last year. I've uninstalled and reinstalled SL several times now, and even wiped my entire computer, and still the same problem. And it logs on just fine on every other computer that I've tried...

Are you running windows Vista on this computer, with an ATI video card? its a common issue right now, and if you look further in this area, there is a download of an SL version that will work for you

Thanks for the advice! Downloaded the Firstlook Viewer and that solved the problem.
