Oups, must have missed the rest of the log file. However, here's the complete error log:
Btw. it told me that it can't find the ships.tbl and when having a look at the media vps files it seem there was no file of such name. Did anyone renamed the ships.tbl and other .tbl files to something new?
I already changed the mod.ini to mediavps_3612 and the colour to 32 bit...without positive result.
