I purchased GC2: Ultimate Edition at a store in mid January 2010. 

I installed everything in the default directories.

The game registered fine.

Several of the campaign files are incorrect/missing data.  As a result some scenarios won't end even when victory conditions are met, the movies between scenarios don't play, etc.  The most common problem is that the victory movie path is incorrect.  Here is an example from the 08_Nightmare.gc2scenario file.

Details=
Title=Nightmare
Image=gfx\Loading\TACampaign_08_Nightmare.png
Victory=We did it! Let's blow this star and go home!
Defeat=We have failed. The Dread Lords have overwhelmed our defenses and captured Kai'vox. All of the shards are once again in their possession. Any hope for defeating the Dread Lords died with the charred remains of the unfinished Terror Star. There will be no stopping them now.
PlayerRace=0
Conversation=Campaigns\TACampaignText_08_Nightmare.xml
IntroScenePath=
VictoryScenePath=TACampaign_Outro.bik
[TEAM]

The victory scene path should start with "movies\"

When I try to use the terror star in TA Nightmare scenario, nothing happens, it just loses its movement point.  Is there anyway to get correctly code scenario files?  I really don't want to have to go into all of the files and fix them myself.

Installing the latest patch seems to make things worse, now the AI messages just say "Iconian morality msg 0", etc (pointers in scenario file don't work).
