Is the amount you're trying to withdraw over the minimum withdrawal? Are you using a valid address? are you trying to withdraw using the programmer mode of advanced mode?
Thanks for getting back to me.
Yeah the amount is over the minimum, I can withdraw the same amount successfully in the web interface. The address is valid, I'm pasting from the same clipboard to both places & it works on the web interface.
For automated withdrawals I'm using the advanced mode. Haven't tried in programmer mode.
