Earlier today I was in SL building. I have a folder there with about 28 underfolders with things i have created. Few hours i notice the whole folder is gone !??? With all the stuff there. I have cleared cache and restarted twice.. But still the folder isnt there. I hve searched for the names that i know shud excist in these folders but nothing appears. Please help me. Its it possible to make a rollback ??? Im a builder and i sell this stuff.
