Technical problems and solutions!!! (all problems and errors are stored here)

To add up.. I tried starting the demo at windowed mode, it crashed at the same place.. but this time an error message pops up...

Application aborted!
.\.BMRender\rmode.cpp(2575): DirectX call failed: -1, -1,D3DERR_INVALIDCALL (The method call is invalid. For example, a method's parameter may not be a valid pointer)

So..the demo doesn't work for me both for windowed and full screen mode..
full screen mode crashes without any messages.windowed mode crashes with that message.
