Welcome to CDRInfo, JDRogers!
Since InCD 4.0.1.0 is buggy, you may try to read your old InCD discs on another box with XP SP1 (here SP1 is crucial), or a box with Win98x, W2K or XP after installing EasyWriteReader 3.3.2.0 (750,220 bytes):
ftp://ftp4.nero.com/EasyWriteReader.exe ftp://ftp6.nero.com/EasyWriteReader.exe (but don't use EasyWriteReader 4.0.0.10, 663,057 bytes).
Otherwise, you may try some commercial CD recovery software:

Sometimes such programs are used with RoadKill's Unstoppable Copier
