Game crashes upon loading a different vehicle

I've been having this problem for a little while now. When go into a map I can drive around in the default truck with no problems, but when I go to load any different vehicle, it removes the default truck and when its "loading" then new vehicle it stops working for about one minute and then closes. It doesn't come up with A error report or any thing. If I try to restart the game or even my computer it just does the same thing. how could I fix this? I've tried re-installing it and it didn't work. I tried to lower the settings in case it's because its just loading too much and once or something like that but that didn't work either.

 

Same problem here but it only happens with cars downloaded from the forum, modded car and original ones works fine. But when i load a new car my previous car disappear and the game crash for 1min before closing it self

 

i figured it out. the graphics settings were to high.
