Audition 5.0, stops recording; trouble

I use Audition 5.0, for a long time; now since a few days,
when I record, the recording stops suddenly
sometime after 6 minutes, sometimes some longer.
I hope someone knows this and can solve this trouble.
Regards Patrick

I don’t think Audition CS5 is supported any longer I am afraid. This means that any issues will no longer be fixed by the Adobe team.
