Is there any chance I can get my AO back fromm LL? I was editing it yesteraday when SL had rezzing & tecnnical issues. The AO is not in my LOST & Found, on my land or in my inventory. I have a very basic copy of the AO, but all the animations, menus and notecards for it it will take hours to fix up again. A big headache.
