Snippy aren't we? You get the free version so you can test drive the product. This is software, not a car. When I get a 90 day trial of Windows Server 2008 or whatever, I don't think I can call Microsoft to open a support ticket for a trial product? Maybe if I pay them a lot of money.
This is a forum for support from the vendor. Other people can chime, in sure, but when the vendor/owner says he doesn't support the free product, don't be a douche about it, because that's how it is - that's the agreement for using the free product. You can't get it to work? Pay for it then. It's relatively cheap for a very powerful product.
Why should the owner spend his time, which could be time spent resolving paid customers' issues, creating new features, fixing bugs, whatever... on someone who has a free version? Easy, he shouldn't.
(...and yes, I know the new server products don't have trials anymore.)
