I spent some time evaluating the product, only to find out that with the evaluation version I could only create one table at a time to SQL Create Statement. I think that you should warn the user what's limited to start with. After I created my first table and went to create a second table it should have popped up a warning that conversion to SQL will be limited to only one table at a time for an evaluation version. This would save a lot of headaches. I think you should have like a 10-table limit, not one.
