Good call doing the test first.

It says the tx doesn't exist, you must have made a mistake, all you do is put your username in the address/username text field on the exchange, then withdraw. I have done this many times from Bittrex after the Steem to Hive hardfork, and never once did I have to use the memo field. I just entered the address. Maybe send 0.1 in a test, perhaps there was fees that used both the 0.01 you would have had remaining to send after the fee.
