I had this problem and fixed it by deleting the temporary files. When I selected the same file that caused the initial problem and the problem re-occurred. Other Zip files played before the suspect one but not after. Rather than delete the file I copied the KMA folder to a new location on the same external drive, re-named the origional folder to Hoster old, then re-named the copied folder Hoster and rebuilt the database. The offending file then played perfectly. The reason I tried it this way was that there may be other files with problems along these lines and if it fixed the one I knew about it would likely fix any other file and save me any embarrassment while doing a show.
