Inter-sim error

When I log in the sim I am currently in loads fine but SL refuses to load any other sim, surrounding or teleport to. If I attempt to teleport to one it will go "Connecting to Region" and then crash. If I attempt to fly into the unloaded parralell sim, it will crash. But when I log back in I am in the sim I attempt to fly into. This means that in order to travel anywhere I need to reboot SL every time. Making the experience a hastle and cutting down on how long I'm playing signifigantly, I've tried Re-installing, Re-patching, Turning off Anti-virus/firewall software, and nothing seems to fix it.

Somebody please help.

Hm. Withouth your computer specs., it can be hard to guess. But my suspicions are that this problem may be a combination of your hardware not been suficient, a slow connection and even a long horizon distance.
Try decreasing your horizon view to 128 or even 64mts. and see if that helps. Then take baby steps, don't go too fast when crossing sim boundaries.

My draw distance is at the lowest and even standing right at the border and waiting the sim won't load. I'm not new I ahve been playing SL for several months and have never encountered this problem.
