KL Web what type of server, os are you running? I did not have a problem installation was seamless, however last year I had spend many hours learning how to install without errors such as yours I have lots of notes ... Are you able to click the "About" link top left, it will show your version, mine is 3.0.0b2.20120117.44 -- also under admin settings there is a license test button.
J.J. Draijer yes there were many bugs however so far the only problems I have found are very minor, I remember it was very unstable last year but not anymore, I have not had to restart yet and I am amazed at just how well it's running very low server load compared to the ices_cc auto dj in the old version, you should try to update or a fresh install.
