Recently, i have been looking for modding options on sins of a solar empire
i opened a file in the GameInfo folder after i backed those files up.
however, i accidentally opened the file in Notepad (the files are .entity), with the "open all files with this" box checked.
Now, when i start a game, the game will get to the loading screen, then stop, and gives me the message that it saved a mini dump

sins-v1.165-2013-12-20-15-19-52-5920-5560.dmp
(there are more, this is the most recent)

Is there a way to remove the open all files with the notepad, would that do anything?
Or is there an alternative to fix the game?

Any help would be greatly appreciated
