BetterTouchTool is currently disabled :(

I started to use BTT from today.
and, after 2 hours setting,
I have just finished to start BTT!
(I didn't adjust anything related to system, just change the key of golden chaos, and some minor things)

However, as soon as I finish my setting,
it become disabled...
why...?

I restarted BTT,
Quited and start again BTT
Checked Enable BTT for...
Updated to the lastest version,
Checked privacy of the MAC setting,
Re-started MAC,

and now, what should I do?

So sad... I spent two hours to use BTT, but...
