I have it installed on 3.0.3 and it's working just fine. In fact, I have about 30 hacks on my 3.0.3 and I have no errors whatsoever! You can find a link to it in my sig, but it has not been grated public access yet. It will be opening soon, so all I can say now is that it works just fine on 3.0.3! I have attached a screenshot for everyone to see that it does work on 3.0.3! Hope everyone that needs help, gets it working soon!
