You paid a license fee to use the products of SimHub...so you go to them with problems, right? If you buy a loaf of bread from a supermarket and it's moldy, do you go to the neighbors and ask what to do? No, you go back to the supermarket. So that's what I'd suggest in this case as well - talk to the people you got the product from. You paid for it, so that gives them the obligation to offer (to some extent) customer support.
