Could possibly be related to the ongoing testnet issue, somehow? https://ethereum.stackexchange.com/questions/12477/ropsten-testnet-is-under-kind-of-attack-what-can-we-do

I have the same issue... is it really a testnet issue? because I can send the tokens to the account but not the ethers. When I try to send the ethers it shows up this message and if I try it fails it should be happening just if there where no enoguh tokens but there are... Which testnet should I use? or justdirectly the main network?
