I just wanted to point you to the general forum where I left a new post. I've deleted the 7.4.x branch from the site and uploaded a new version to the 7.3 branch that works with WotLK 3.3. This doesn't mean 7.4 is going away, it just needs some work before it's released as a download.
If you upgraded previously to 7.4, don't worry, your frames will convert back to 7.3 with no issues.
