Well, Basj, I submitted a support ticket on this issue, and the response that I got was:

We use our forums for support so as to help the most people for the longest period of time. If we work tickets for support issues, it helps just one person and just that one time. The forums are staffed with support personnel, developers, and seasoned users of our products. You will be well served there.
In other words, don't create a ticket for your problem, just post on the forum... yes, *this* forum...
So permit me to repeat my original request...
