I'm a Mac (OS 10.5.8, so yes, I'm behind a bit.) user and I had been able to use Firestorm until last night when the sim I was in either crashed or restarted, and then Firestorm had it's major update, so I figured I might as well grab it while I was offline. I installed it over the former version, and found I couldn't launch it. I keep getting the "Application has quit unexpectedly" message, so I decided to try to restart. No avail. Clean install? Nothing. Deleted every trace of SL from my computer? Nada. I can't get a single viewer, third party or not, to run on my computer, and I have no idea why. I'm a paid member, so it would be cool to, you know, get on and get a use out of what I'm paying for...
