I tried hitting the record animation button and I immediately received that same french error. I hit the OK button acknowledging the error, but VWD is still running in the background. I can press the stop simulation button and it stops. But if I then again press the start dynamic simulation button I immediately get the same error. And if I just let the simulation continue it goes on and on and produces no visible results.

I have my VWD files set up as C:/VWD if that makes any difference. They are not in my actual poser directory substructure.
