I just need SL to work... please... I'm beggin... I can't get the main or firestorm viewers to work on the main OR beta grids. I've cleared my caches, restarted my computer... argh.
Allegory: No, usually it lets me in but it's not letting me successfully upload anything, my animations get stuck, clicking on scripted objects is unresponsive 3/4 of the time
i've found alchemy viewer to be way more stable/less laggy since PBR. they've been working on the others (and i haven't tried the latest official), but white firestorm's gotten more usable than it was, alchemy is still better for me.
booo. it's obnoxious, but you might want to uninstall all viewers and reinstall one. sometimes viewers go....bad, and cause issues. but maybe hit upSpeedtest by Ookla - The Global Broadband Speed Testfirst and see how your internets are treating you at this point too, in case it's a slow connection.
(when the official viewer went bad for me, it was eventually really...dramatic, as textures would explode into rainbows and crash. but it was rough for a while before it got to that point)
