If it had been $10, I'd say you got scammed. For 35 pounds, I would give it a chance before assuming you got scammed.
Blue Soleil support sucks, so this might take some work. I've always just purchased BS licenses.
Here are some thoughts:
1. If you don't plan on doing any BT programming, you probably don't even need Blue Soleil. Most bluetooth dongles are capable of working with different BT stacks (MicroSoft, Widcomm, Toshiba).
2. What version of Blue Soleil came on the disc?
3. Have you activated your license?
4. Here's some tool that might help.
