Ok so I need to log into SL viewer to upload listings to my MP store, but I CAN'T GET IN!!! I'm not even getting errors. The SL viewer loads up just fine, but when the progress bar hits "loading world" it just gets stuck! My friends claim I'm logged in but I can't see anything! I have updated the viewer and done at least 6 clean reinstalls, so what now? Until this is fixed I can't upload anything to my MP store since no other Mac compatible viewer I know of has VMM. What do I do???
