Can't leave Hydlaa - crashes when moving to new map (solved!)

[Tumaini]

At the moment, I cannot leave Hydlaa.
When I try to get to Ojeveda the client crashes when it tries to load the new map in among the cliffs on the road out east of Hydlaa.
The client also crashes when I try to go through the forest from Hydlaa towards the magic shop.
I even got stuck there crashing for a while, until a GM moved me into Hydlaa again.

The message I get is:

Code: [Select]

Something unexpected happened in PlaneShift: Steel Blue
Details: EXCEPTION_ACCESS_VIOLATION at 69390F62

Would you like to save a diagnostics file?
This also happens when I try to use "Load all maps" in the setup utility, and try to log in in Hydlaa.

Does anyone know a solution for this?

UPDATE: This was solved by setting "Vertex Buffer Object" to Off in the setup utility.
However, the map now has big black patches of weird texture.
