physX_open() causes error

Hi,
I've been trying to get the PhysX engine to run, but it just won't work. Every time I try to call the function physX_open(), I get an error that says that PhysX cannot be initialized. I've tried re-installing gamestudio and I downloaded & installed PhysX using the installer on the nVidia website. I still get the error. Does anyone know this problem? Does anyone know how to fix it?
Thanks,

Hello
Have you tried to make as simple as possible project first which would have basically just the main function and the physX_open() function, so that you can be sure that there is nothing wrong else where in your code?

I don't know but somethimes I get an error with physX_open when I've changed something at a block(I'm 99.9% sure that is has nothing to do with my code)...

ok
Have you tested some game from internet which uses NVidia's physics engine and does that work?

I was getting one, when I add wheels to car and used event flags on it.

Thanks for the replies!
The reason why this worries me is because I tested a piece of code that I downloaded from the gamestudio website somewhere. It was an example using the PhysX engine. I didn't modify it in any way, and I still got an error. I think it was inside the workshops, but I don't remember for sure (I posted this topic about 3 months ago).

Simply calling physX_open(); inside function main() {} without anything else also causes an error.

You mean this one, it works well for me.
