I tried to withdraw my EOS from Simpleos wallet but was getting " Error: billed CPU time (286 us) is greater than the maximum billable CPU time for the transaction (0 us). So ,I decided to stake some more eos to enable the transaction. I have ended up (by accident),staking all of my eos (90% cpu and 10% net). Now I am trying to unstake them and I am getting the same error. I am not very tech at all and was only wanting to withdraw, can anyone offer a solution please? Thanks in advance.
