WTF. I logged in on the new viewer because it was the only way I could change some group role settings. Ever since, I can't get more than...
about 25K of my inventory to load. I have almost NINETY THOUSAND items. I've cleared cache and relogged.
Nothing is working.
holy crap, not good 
yikes!
Clear cache and relog straight to an empty sim. One that I use is Kara. Then wait a few minutes as it loads.
