My Dracu-Riot earlier in the day was working just fine, I saved and existed the game to go eat for a couple of hours then came back to find this unusual error.
This error is one that I have solved many times by simple putting the version.dll file from the Win8WOH.zip in the installation directory (in fact I had to solve it in order to start playing the game). However, even though I have been playing with this file in the folder for over a month, all of a sudden the game stops working.
Things I tired:
Downloading and placing a new version.dll file
Restarting the Computer
Changing the system local from Japanese to US and back to Japanese
The last thing I wanted to do is reinstall the game, but I would prefer not to go thru the hassle again.
