Yeah, both of my machines (one with dual 5870s, and one with a single 7970) will get tasks from moo, but not run them. And like I said, this problem is not unique to me. Other people in the forums are having the same problem. However, I did find an app_info.xml that does work. Don't let the app names throw you, like they did me (at first).
On a side note, is there any trick to getting moo to run on 7970s? Now that I have it running, I get nothing but errors with that GPU.
