Yes, it's because all my BTC are in Jaxx now!
Are you sure you are selecting the "bch/livenet" chain instead of the "btc/livenet" one? Since the tool is showing your BTC balance instead of the BCH available, this may be the problem.
Or you can join Copay's beta test which already has support for Bitcoin Cash directly from the wallet.

Ok, so, I selected "bch/livenet" and it said: Available balance: 0.00000000 BCH. Insufficents funds.
I put my Recovery phrase and my Backup Password.
It's really weird... Why I can't find my last private key, wtf...
If you had already transfer "out" the Bitcoin Cash to another wallet then you dont need to look any further to Bitcoin Cash in that wallet BUT I think its important that you must select BCH/Live net as TryNinja told you AND refresh the Tool website with F5 before doing any new check. I have confirmed that if you go back in your browser it gets kinda glithy
