> Delete all "global mix cache.dat" and "global mix database.dat" files from your HDD.

Tnx Olaf, it works, but there are still some problems:

there are even less names now. (If you open the ra2.mix/local.mix the voxels and hva files don't have a name)
I finally found the Terror Drone but its a shp and not a vxl.
So...
I then saved the shp as a single pcx file.
And then i can save the pcx as a vxl file.
But...
When i try that i'll get the same error as before.
So...
Is there any way to make a vxl out of that shp/pcx file??
