I downloaded and installed demifail on my computer.  Double clicking on the exe or on the application in impulse results in the demigod simply failing to start up.  I have verified this through windows task manager:  On double clicking the exe it appears in the task manager for a split second and then dissapears.  No crashes, no exceptions, no stacktrace, nothing.

I am running windows xp, not using webcam or skype or commodo and my drivers are up to date. On very rare occasions demifail chooses to start up but this is rare.  I do nothing different when it DOES work. Its just one day it refuses to work, others it works fine. 

I have demigod on another computer which is unpatched as I had given up on this game 6 months ago.  I tried to patch it last week and got an md5 mismatch for the downloaded file (go figure).  Tried downloading patch a 2nd time with same result.  In short I have 2 computers that cannot run / update demigod.

Any takes on this besides telling me to uninstall / redownload and reinstall?
