I just posted a question about this, It's not my Wifi since I just switched over to an ethernet cable and it's still crashing (has been for 2 days). It's possibly my avatar/account, though I've been able to log in on the text viewer on my phone. I created another account, and SL runs smoothly, no crashes at all. I don't want to have to switch accounts due to the amount of money I've put into my main. Is there anyway to fix this? I've done a manual clear cache as well. No such luck. Just as a reminder! I have created a new account to test if it's my computer or the viewer, and Second Life has run smoothly on that new account.
