Don't give up guys, the latest version has even more features, song request widget, running very stable also.
What os are you installing this on? I just installed a second v3 this morning , I had to install both SC1,2 and ices_cc , sc_trans by hand but it's so far doing great. Are you installing on a server with the old Centova on it?
I had problems when I tried that, Centova V3 has everything needed other than MYSQL, I think that it's best if you install on a fresh machine with only Centova and MYSQL, I use CentOS 5.5 x64 MySQL
