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.
