Just a suggestion.
Audiocatalyst is not all that good at the job its doing.
As a recommendation, try one of these programs.
CDex is user friendly as it includes all the necessary things as one whole package rather than making the user download different packages.
I recommend using CDex with Ogg Vorbis on Quality Setting 6.

The slightly more advanced (and the best) is Exact Audio Copy (EAC).
It does a 100%(or as close to it depending on the quality of your CD) copy of the music that is on the CD. Audiocatalyst doesn't do a very good job of it (slight problems here and there...)
EAC coupled with LAME or Ogg Vorbis is a potent mix.
LAME is a mp3 codec which is by far the superior codec available atm.
Use the r3mix settings for a high quality rip.
Latest LAME binaries
Ogg Vorbis is a Open Source, 100% license free music standard that is on par with mp3. Its starting to gain some fan base but not quite the same amount as mp3 =P.
Ogg Vorbis on Quality Setting 6 is the same as LAME r3mix settings. avg 192kbps.
