There is an update to the game here:
http://www.funlabs.com/cora3/
This fixes the garage-problem that occurred when buying a truck.
To gain running-time on your notebook open EngineDll.dll after the update in your fav. hex-ed and go to 0x29A8AC ... if you see a 0x1BC0h there change it to 0x33C0h... that's all!!!
