If you only have the ProPak or MegaPak, I suspect that you just don't have the underlying RealTracks referenced by the _JAZFRED style. As suggested, make a copy of the file first. Then unfreeze all the tracks. Then look in StylePicker to see if you even have that style (or if it shows N/A). If you don't have it, the first thing I would do is open RealTracks picker and rebuild that list, then open StylePicker and do a slow rebuild of that list, then look to see if you have that style. If not, then select an alternate style you do have (preferably a RealTracks style to make sure they play properly, since you've already validated that MIDI styles play). Validate that the song plays with the substituted style.

It's at this point you just go with the substitution, or look towards upgrading to a Pak that has the styles you want, or just buying the StylePak that contains _JAZFRED.
