Soglos Karaoke Pro last version

[BigMac]

I produce Karaoke Videos with Karaoke video Creator as basic soft. But this is only nearby. Lots of KJ's I know work with Siglos Karaoke Pro. One of them, a friend has a problem with it every Event he makes. It is always the same story: Close to the end of the Karaoke Event, after playing about 60 Songs (not exactly, sometimes more, sometimes less) Siglos stops with error: Not enough memory. Then he has to reload Siglos, and everything is fine. This prob another KJ also has. It happens on Win 7 and also on Vista.
Independant if x86 or x64. The actual machine is a Win 7 x64 system with 8GB RAM. As I can can see (I am an IT) the soft collects some fragments of played Karaoke (CDG and also MPG1 and 2 are played) in the memory anyway and when it is too much, the memory is full. Do you have any idea?
