It's been over a week of troubleshooting with no luck. Help? Answered 02 Jan: Hi Nya, This one's a stumper. You crash on two viewers, but only on one of your avatars. You've done all the things I'd have recommended, with the exception of tossing the viewer's "saved state" folder. I added instructions for doing that in the comments of the SLV clean install KB page here... http://community.secondlife.com/t5/English-Knowledge-Base/How-to-uninstall-and-reinstall-Second-Life... I don't think that added step will fix anything for you. If you have access to another computer, or run Windows on your Mac, you might try installing a viewer there and attempting to log in. If the problem persists, then through some mechanism I don't understand, the avatar, or what it's wearing is exposing some bug in the viewer. If you are able to log in, try stripping off all attachments, then return to your finicky Mac and try again. I don't think I helped, but I do wish you luck. Marie: Thank you for your suggestions. I did try deleting saved state folder while doing another clean reinstall. Didn't fix, as you predicted. I do not have access to another computer, sadly. I upgraded to a premium account and submitted a ticket. :(
