Why do I keep gettting strange error reports?

[David51]

I installed the key error file in the finder with the one that came with the help video. But I now get even stranger error reports-after loading the Sopranos Multi I open a new instance of choirs on the next track and chose Altos which[repeatably] began to load but stopped and the "Can't find that file window" opens, but it says it can't find the sopranos, but I am loading altos,why does this software work so strangely?

And there is no audio output from Logic, despite the activity seen on the track header mini level meters, I have tried all the normal solutions but since installingEWsoftware there is no more audio output, maybe I set it up wrong. But that wouldn't explain no audio from projects with no Play instance in them.
