CRASH TO DESKTOP WITH LIVERIES INSTALL

Hi GUys !!

I have this problem with the 737! I install the product with the latest service pack then i install the liveries i need and i start the simulator and all is ok ! Then after two three day using the plane i install another livery and when i load the plane i have the DLL of the panell that ask to be loaded i click on run the plane is loaded when i click on start flight the panel doesnt initialize and crash to desktop so i always have to disinstall the plane and install it again and it is already 100 times i do it. Any 2-3 days i have to disintall the plane all liveries and install them all again. another change i made is about the view of the plane in 2D PAnel and the change is the followed:from VIEW_FORWARD_DIR=10.000, 0.000, 0.000 to VIEW_FORWARD_DIR=3.3, 0.0, 0.0. I made this change to move a bit up the view in the 2D panel. Other than this all is as from installation... Anyone of you know what cause this problem. The direct X is loaded normally. I run the simulator on windows 7 64...

Thanks
