Yes, I have exactly the same experience. I wrote to them a couple of days ago about it and have not heard from them. I also tried to buy the plug in on line instead of the demo so I could get past the 90 minute thing and the KAGI e commerce thing doesn't accept my credit card which is functional.
So there is really no support which you probably have found.
Does anyone have a file example for the troi- url plug in that actually works and we could see? Thanks
