Umm yo Impulse, that's the wrong folder.
Impulse is putting Twightlight of the Arnor 2.0 into the wrong folder.
Ok so I updated Dark Avatar and ToA to 2.0, tried to play it but it complained that my Dark avatar wasn't up to date.
so I checked it and sure enough Dark Avatar was showing 2.00 on the little version number inthe corner of the screen...hmmm.
I open my GalCiv2 folder and to my surprise the updater hadn't installed ToA to the ../Twightlight sub-folder, it had installed it to my main GalCiv2 folder!
Dubbya Tee Eff Bee Bee Que. I've spent most of the night comparing files to see which ones are newer and moving them tot he proper folder, i'm not sure how this happened either, I haven't investigated the WHY of it, but now I know what my problem is. I'm probably going to end up uninstalling and starting over from scratch.
