freespace 2 problem with mediavps mod from Knossos

[Marik]

So have freespace 2 on steam downloaded, downloaded the knossos installer etc - loaded the upgraded graphics mod media vps - i click on the play button in the knossos launcher thats associated with mediavps - can do the first 3 tutorial training missions with the updated graphics but when goes to first actual mission for campaign it doesnt run and crashes back to the knossos main screen.

The freespace steam starter shortcut and the knossos FS2 campaign shortcut/play buttons only get me the original graphics from original game and they work to play beyond the first training missions - Am I missing something or some step to get the update graphics with these shortcut buttons?

Thanks in advance.
