I got the CM7 installed on my HTC Wildfire. The trick is that you need to get your phone updated to Wildfire S to proceede to get CM7 on your phone. I'm not sure what you have installed, so I guess you need to read on some more to get it done right.
And to have it said, it was a friend of mine that opened my phone, and he's good on opening devices etc., and he spent like 3-4 hours to get it done. I guess the one that had your phone first didn't know that he had to open it to an HTC Wildfire S before he could open it in a new ROM. =/ Sorry for not having anything else to help you with at the moment. Hope what I've written here can help you some.
