Missing track 4 in presentation

[renegade]

Presentations are not opening correctly. Data usually displayed on the right side of the log, is now jammed in the middle of the log.

When we open a log file, and view the presentation options, one of the tracks (track 4) is not listed at the bottom. On another computer running warrior, that is working, there is a track 4 listed on bottom of presentation options.  Im guessing the missing track 4 is the problem. How would i get this back?
