Windows version spontanenously decided to refuse to start

[rnjacobs]

I'm using the Humble Bundle version on Windows XP. I played through the first 17 levels. I go to start it today, and the program immediately exits without an error. It might be a resolution thing—I was playing on an external 1920x1080 monitor but now don't have access to it. Help?

I'm going to have to add this to the FAQ/Support as it's a common problem (still haven't decided the best way to resolve it).

On PC, go to My Documents/EufloriaHD and delete OptionsData.bin.

You won't lose progress, it'll just reset your graphic options.
