There is a limit in VWD about the number of springs generated to keep VWD responding. That's the error

There are many solutions to prevent this: if you are using DS4: is there a subdivision level ?, in VWD there are many options to reduce the number of vertices go in the manual (not in front of my computer), use Decimator (last solution for me)

My advice would be to start testing VWD with basic simple clothes, then more complex clothes, hair, animation,....
