SL has been working fine on all release candidates up to the most recent - I installed 1-20-2-85278 today and cannot get into SL at all. It crashes just after login every time, while the world is resolving, then there is a long wait before it will let me log in again (typical 'system is logging you out, please try again at X-hours' message). At one point I managed to resolve in-world but then could not teleport to one of my usual sims, tried to tp home instead, and crashed en route. I have gone to download the main client instead until this is fixed!
