Refresh didn't work, but here's a console log output that may help you diagnose the problem better:
"Error: 10 assert_exception: Assert Exception
available_shares >= op.vesting_shares: Account does not have enough vesting shares to delegate."
and a big list of debug code follows, which I don't know if I should be sharing or not. Figured this alone might help you help me :P lol
Looks like you are trying to delegate more SP than your account has available. But again, this is a Steemconnect error.
I dont see a way to contact them for support, but it says the creator is busy.org
Actually if you check this post out it looks like your error is complaining about too small of a delegation.
That post claims there is like a minimum of 2 SP. (~4k VESTS)
