Sound Juicer not reading cd's

I use OS 11.4 64bit with KDE, and had been using sound juicer to ripp my cd colection. It worked perfectly with about 30 CDs until I got this message and since then is the same thing with every cd I try to riipp

Could not read the CD

Sound Juicer could not read the track listing on this CD.
Reason: Cannot access CD: The specified location is not mounted

the weird thing is that I can play the CDs in any other program. They read just fine.

this is the return from konsole

Any ideas what might be causing the problem?
