@All who have problems: We have checked your cache files you have sent to us, and we have found that you have exactly same issue.
The problem is with the "Minimum" settings, it simply doesn't work as intended.
For some it works, but for others - doesn't. This is a thing for us to find out what causing this. Issue is logged and will be investigated.
You should be able to get in after doing following:
0. Be sure you don't have AW running
1. Delete the contents of the "Cache" folder
2. Launch AfterWorld
3. At login screen click on "Options" and select "Low" quality settings in "Video" section
4. Press "Apply", "Close" and quit from the AfterWorld without logging in.
5. Restart AW and double-check that you have "Low" settions via Options panel.
5. Try to get into the game.
Post your results here. If you still have problems - send your cache folder back to us again, so we can look what can be wrong now.
P.S. Additionally, check that you have latest drivers for your video card, if not - download new ones and install.
