No George. This is the way it has ALWAYS worked since I had Hoster:

ie. I have a disc (Custom Assembly) Disc is #16. It has say 20 songs on it. Different mfg. SC, CB etc. Say song #3 on disc 16 is a CB mfg. I might want to replace it with a SC version. The song # (bookid is 1603). I would use Micro Studio; record all tracks with the exception of #3. I then re-record the disc and insert the SC version for #3. I then have a new custom assembly disc. I would take it, put it in the drive, bring up Hoster, import, type in disc 16; all the songs would show on the disc. I would simply check number 3 and re-import. Now bookid #1603 would be same song just with the SC version instead of the CB version. It's alsways been so simple. I've never had to delete anything. Just can't figure out way it no longer is allowing me to do this. I will try it again when I get home tonight and if all else fails will try your suggestion about delelting the intire disc and reimporting from scratch.

Thanks for the help.
