Ultrastar not detecting songs and freezes

[Tor Harald Thorland]

Binary package hint: ultrastar-ng-xine

Ubuntu 8.04, Ultrastarng 0.1.4
When installing and trying Ultrastar it does not work. The main screen pops up.... hitting S button does nothing, Hitting P gives me another green screen, but nothing more,..
I've tried to add songs as described on the net, but looks like it does not want them.... also it shows a doubble // in the path for the songs ?!?
From command line it gives me this:

tortho@tortho-XPS:~$ /usr/games/ultrastarng
Using /usr/share/games/ultrastar-ng//songs as default songs directory
