Using Wine will probably work

I should add that instruction to the game's description, glad I could help! :)

that's really strange, if the exe is inside the data folder, try moving it outside that folder and then launching it, make sure they are in the same parent folder.
If its already like that, you can try renaming the folder to Data, or from what I've read sometimes a restart can fix it.

And if none of this works I'll rebuild the exe and upload a new copy, though I'm not sure why the data folder would be corrupted.
