Made a mess of GSB folders

I am a simpleton with computers. Bought the original game back in May 2010 and the Swarm expansion a month later. Just now bought the Campaign mod. Trouble is, I didn’t save the mod into the same folder. I couldn’t find the campaign mode in the basic game, so I’ve just tried pasting things around to fix it…anyway, I’ve stuffed the whole jolly lot.

Is there a way of resetting the folders so things work, or have I got to unistall the game and buy it again?

Suggestions greatly appreciated.

Best idea is probably to delete everything and reinstall. You don’t need to buy it again to do the installation - if your download link has expired then drop Cliffski an email from the address you used when you bought it and he’ll reactivate the link.
