Depends on the template.
I've never bought from TM, but I've bought from others. They usually come in two forms:
One, is that the Flash file reads all of the information it needs from a .txt file. That one is easier than anything to configure.
The other one is that you have to edit the Flash file manually, with a copy of Macromedia Flash. Some of them aren't that hard, but I've come across some that have been such a pain to configure that I gave up on them.

or something and place a bid request for a Flash designer.
