Ah, ok, thanks. Is that new, or was it previously automatically selected?
Sorry, I just realised that I confused you with Kaskuya. The rule set is needed by the generator to generate a history. It's what the generator uses to decide which laws to pick from, and which gender a character should be. Things like that.

What do I do?
For a start, you've selected the wrong path, that's why it's saying that it can't find CK2. You need to select the directory with the .exe file in it. It looks like the ArgumentException was caused by it trying to find CK2 in a blank path. I'm guessing you selected the path box, then clicked somewhere else in the program.
[Edit] I've uploaded version 2.0.13 which fixes a couple bugs.
Version 2.0.13
- No longer allows data load without a rule set.
- Prevent program attempting to find CK2 in a blank path.
- No longer throws error if mod directory doesn't exist.
- Fixed default settings not having a ruleset checked.
- Now outputs list of unchecked required rulesets.
