Are you still in clockwork? what is the name of the file you flashed?
Luckily, you can mount the phone as a usb drive from clockwork. Just connect the phone to your PC, head to the mounts and storage menu from the main menu in clockwork, then mount usb storage. The drive should appear in windows, from there just copy the CM7 zip file, the google apps package and the lordmod kernel (there's no need to unzip them) and flash in this order:
CM7.zip -> Google Apps Package -> Lordmod kernel.
