When I first installed the game, I noticed the Skirmish Arenas were locked, and all the Dark Matter levels were locked except # 3. I've played through all 25 levels, and got a box that said it would unlock the Dark Matter mode; I clicked OK. Nothing seems to have changed- #3 is the only one available. I tried using the Unlock option, and restarted, but no change.
Is this normal or a bug?
I was thinking about uninstalling and reinstalling. Is this a possible solution? If I do it will I lose my progress? Actually, this is not a big deal for me, since I'd like to play through again. If it is retained, though, and you think it might be related to the issue, should I delete the file, and if so, where is it?
Any help would be appreciated.
