Kingchris, thanks for your efforts on this - mine is now working with OTA HTC 2.2
I haven't been able to find anymore detail on this issue so i thought i should give other users the heads up in your post - i was having the same problem but now when attempting your version i'm getting the message ''Out of Date This copy of adfree is too old, please update to a newer version''
You should remove the ''install-adfree-windows-step2.bat" from the instructions and advise to download the latest version and install .
Worked for me - thanks again!
