There are three missing chapters in the StopTazmo archive for this series -- chapter 23, 27 and 34. In addition the archive's version of chapter 22 is low-quality (and not one of mine).
The missing chapters and a better-quality version of chapter 22 can be found in my 4shared directory at:
Chapters 22, 23 and 27 are in the volume 4 directory and chapter 34 is in volume 5. Hope this helps.
