the logfile shows that you tried to load Grundorf V 3.0. In that special case there is a parklist error in line 113 of your logfile. Navigate to the map folder of Grundorf V3.0 and look for the parklist.txt. Open it and try to find an entry that looks like that: vehicles\HC_KIPKW6\parked_hckipkw6. Delete it and start the map again.
Regarding all the other maps: Please post logfiles for all maps seperately as every map might have individual problems/missing objects.
