Playback or Hear Functions inoperable

I just downloaded and installed Lime. It all seemed to
go fine until I tried to get Lime to play back the score.
I hooked up the clocks in the Patchbay setup as
suggested in the manual. I have a Performa 476 with a
68040 processor and Mac OS 8.0. I searched for a
troubleshooting guide and found none. I turned off the
Virus control and the screensaver. I also clicked off the
icon which shows the notes in the uppermost left part of
the lower panel. Am I missing some step here.
Also can Concertware files be imported into Lime?
Thanks for your attention.
