[Issue #275] Add catch for when activation shortcut is not set

[tulburg]

Issue 275

This is my best guess of what happened. And since reinstalling and launching again has not visible window, I assumed it wasn't launching.

Further suggestions:

• Maybe always launch the mainWindow at every launch. LaunchKey is usually the first I want to see at login

I need this fix! I can't open the app.
@tulburg, did you find a way to run the app?

[tulburg]

@ivomota yes, but I would not recommend. I deleted all preferences (application support etc) and reinstalled. Then painfully set all my shortcuts again

I think, if you open the app by double clicking it, wait a sec, then hit cmd+, it'll open settings?

I like your logic here though @tulburg.
