wich download did you do?
reading the first post on the developers thread, he has 2 downloads listed... one for lockwork 2.x.x.x and one for 3.0.0.7 and up.
heres what is prolly the easiest course of action:
1)download an app from the market called "scary aliens android file verifier" to your phone
2)go back to the xda thread for warmtwopointtwo and dowload the 3.x version to your pc
3)relash the latest clockwork on your phone via rom manager (3.0.0.8)
4)transfer the file to your sd card via usb cable
5) run the app. press chose file. scroll down till you see the download you just transfered. long press it and chose md5 sum. compare the md5 sum generated by the app to the md5 sum listed on the xda thread for the 3.x download ([MD5Sum: 5ca34912d800a5120349a09cdf5a10b0]) they should match. this ensures that you got a clean,complete download.
6) boot into receovery however youre comfortable doing it
7)make a backup of your current rom. wipe. flash warm z. reboot
