Assuming you purchased the app from the android market and didn't obtain it from other sources ... Why not use the "email developer" function within the market?
Yes I purchased it, it is my only purchase. I couldnt get a refund because it took me more than 15 minutes to download 96 mb.
Using the email developer funtion within the market yeilds a canned response asking me to take extra steps to contant them.
I'm now back on ThundeRom 1.6.2, tried all the build props. I dont understand how it works on some phones and not on others. I was placing the blame on being rooted/different rom so i went back to stock which also didnt work. I am starting to believe that it could be from the hardware.
