I can't send from my REP wallet! (0 spendable and receiving error message)

REP runs on the Ethereum network so it requires a small gas cost to perform transactions. 

If you are seeing this message "Some of your REP-holding accounts require more ETH to be able to transfer", all you need to do is send a small ETH fee to the exact ETH address listed in the error message. 

Please find the exact address displayed in the blue notification bar by going to Menu -> Display Private Keys -> Display Ethereum Keys, copy the address to the clipboard and send a small amount of ETH (0.02 of ETH should do) to the address in your Ethereum wallet by pasting it to "Receiving Address".
