Asset upnp trial version R7 on mac

[macca75]

Hi
I'm using Asset UPnP R7 trill version on mac to load already ripped albums onto my Cambridge audio music streamer. All works fine up to around 950 tracks but then when i add the next batch it hangs on scanning library for over an hour and when it eventually finishes scanning it reports 0 tracks 0 albums.

Is there a limit to the number of songs you can include in the configuration of the trial version and i just need to buy the restored version, or is the problem something more sinister.

Thanks in advance to anyone who can help.
