as of hotfix 3 still no luck.
I've deleted saved folder, deleted options.lua, set preload radius to minimum, increased my pagefile to 16gb, tried loading instant action missions prior to joined mp. Nothing has worked so far, and It's starting to really bother me. Its been 3 weeks now since I've been able to join any MP server. It just take forever to load, hits the plane list, freezes and either goes black and crashes or goes directly to main menu after about 5-10 minutes of loading.
