Hi,
Did this get resolved?
Anyway, if transactions already occurred for your account you have to pay MyMonero an import fee of 1 XMR. There is a simple way around this though. Note that you need your 25 word mnemonic seed for this.
[1] Go to this page and download the Windows binaries.
[2] Extract the binaries (.ZIP file) to a directory of your liking.
[3] Go to the directory and open monero-wallet-gui.
[4] First change localhost:18081
to node.supportxmr.com:18081
.
[5] Then choose "Restore wallet from 25 word mnemonic seed".
[6] Enter a wallet name and enter the 25 word mnemonic seed of the wallet generated with moneroaddress.
[7] Now follow the steps in the wizard.
[8] Lastly, the wallet should start refreshing and your coins should show up when you are fully refreshed.
