Can't do anything after clicking "Arc Eternal" except for "Return to Origin"

[timmy]

Hey there,

I'm using the Mac version from Steam. It used to work, but I've come back to it for another play through and can't seem to start any missions.

Basically, the main screen starts up fine, but when I click "Arc Eternal" to start the story, the screen I get to only has a rotating ship, I can zoom in and out, and click "return to origin". There are no planets to go to!

I am getting this error in the logs:

The game can't read (or it is corrupt) the save game dat files it needs.  On the mac, I think they are stored here "~/Documents/CreeperWorld3/".  This can happen because of file corruption, or because macos decided to quaranteen the game, etc.  That shouldn't happen because it's a steam game, but.... 

In any case, there is a missionstats.dat file in ~/Documents/CreeperWorld3/ that the game needs access to.  You can rename the creeperworld3 directory under documents and the game should create it again.  If not, there is a file permissions or access rights issue.
