Greeting,
Friend, you can try a simple thing, just change your viewer,
http://wiki.secondlife.com/wiki/Third_Party_Viewer_Directory
or If you want to fix your SL Vewier to see your objects
Kindly follow these setup
1. Open Preferences → Network & Cache
2. Go to the first path “Cache Location” and click the “Open” button behind the path. This will open a file explorer window displaying your current cache location. (You can also look for the %APPDATA% location on your computer.)
3. Logout (close the viewer) and then delete everything inside the cache folder displayed in your file explorer.
Now continue as follows:
1.Log back into SL, to a quiet region (try Hippo Hollow,Aich or hatton). On your inventory window, click “Recent Items”.
2.Wait for your inventory to repopulate fully. The process may be sped up, if necessary, by typing random letters into the search bar.
3.While inventory repopulates, do not teleport anywhere, and do not attempt to access anything in your inventory. Talk to people or surf the web, or just go out for coffee
4.Watch as it repopulates. As long as you can see (Fetched…) at the top of the inventory window, it is still loading.
5.Once inventory has repopulated, log out of SL once more, then log back in.
