Error send funds from Galleon Wallet - What does this mean?

backtracked, backtracked(temporary: proto.015-PtLimaPt.contract.cannot_pay_storage_fee), (temporary: proto.015-PtLimaPt.contract.balance_too_low), (temporary: proto.015-PtLimaPt.tez.subtraction_underflow)

Hi, this error means that there was not enough funds in the account to cover the transaction fees. Try setting the fee to 0.00142 xtz and leave behind some small amount of xtz.

When will Galleon work?
