Odd, I just d/l it from the market and it installed fine on BB v0.7 @ 1G. Several people reported problems last night (some couldn't even see it on the market) I would try again as they may have released an update in the last few hours.
Edit: just double checked and it runs fine, even after rebooting.
try using the barcode scanner and just get it from an online source. there is one on the home page of droidmod.org, just scroll to the bottom cus it is an older post. I hope this helps
