Crypto-Bridge will close accounts on the 15th December, one week from now.

I was able to get verified with KYC and send BTC.

BUT i can not send the BTS i have in my account.   I want to send to Bittrex (most simple way, or should be)

I enter. Registered account name:  bittrex-deposit
then the memo:

Then i click send and get a new message on crypto bridge saying.

"Transaction was not signed. Do you have a private key? [no_signers]"

What does this mean please and is there anyway to send BTS from CryptoBridge of they simply scamming users and stealing peoples BTS?
