Problem with CD Baby cds

Sorry if this is the wrong place to post.

I just received 6 cds ordered and manufactured, (apparently) by CD Baby.  I opened a couple and played them on my computer.  Worked well.  The next night I tried playing them on my system using my Cambridge Audio CD transport.  I got nothing but "error" messages.  The transport can not read the cds.

Any suggestions?  Comments?  I would like to keep the cds but obviously would like to be able to play them on my system.

Thanks in advance,

Bob
