Concerning problem 1 after testing alot of things I have figured out that i can compile lvls. but I can't run the lvl even if its as simple as a small box with the default texture. Does anyone know why this is happening?

As for problem 2 I read up on it more and only found these +'s to haveing Pro.

1. a file packer which compress all artwork into a tiny encripted resourse(dont exactly know what that means or does)

2.One year of support(I can see this to be worth some extra money)

3.renders huge lvls faster(Nice but how?)

If you know of any other +'s or answers to my question again they would be appreciated.
