So, I just picked this game up the other day because I felt like a good dungeon crawler and this game has a great reputation. So far, I love it. Problem is, the first night that I played the game would let me set my resolution to 1920x1080, which made the game look great for its age.

Now, a few days later I go to play it again and it was set to the lowest resolution and my settings had been erased. As well, it will not let me go above a resolution of 1280x1024. This is really bothering me because the game just looked so luscious at 1080 and no matter what I do, even editing my config.ini, I cannot repair this issue. Anyone have any ideas what to do?

Are you running as administrator? Might be a permissions issue. Alternatively you could try installing the game somewhere other than program files.

It also could be caused by somehow getting stuck with 4:3 resolutions only... if you enable widescreen the option for 120x1080 might come back. I've seen that happen in games before.
