For absolutely no reason I can discern (they were working fine before and I didn't change anything at all), both Creatures 3 and Docking Station now give me this error when I try to start them, and if I click "Continue" I just get a black window:

Catalogue Error: CLE0012: Index 3 out of range 0 to 0 for tag app_insufficient_disk_space

It's just the default GOG installation. I completely uninstalled and then reinstalled using the GOG installer, and still get the same error.

I had this error before. I am using Windows XP SP2 and all I did was uninstalling the game and installed the game into my C Drive instead of D. It's becoming my habit to install games into D drive since it has a lot more disk space than the C drive.

So if anyone having this problem install the game into the C Drive. Works for me. Hope this helps and have fun, guys ! :)
