Importing mp3 with cover art

I sometimes purchase backing tracks from a company that offers them in idivdual tracks, drums bass, piano guitars etc.
 
recently  on X3 I can't import them and I get an odd message stating out of memory.   I'm on a dual boot system, so in windows xp on sonar x1 I can import them.
 
I inquired and was told they are including cover art now.   So does that makes sense to get an out of memory message?
 
and is there some software available to strip out the art work from mp3's?
 
 

Thanks for the info.
