==The new wallet defaults to Sending your private balance that were anonymised with the Lelantus protocol.
This can cause the "The amount exceeds your balance" error to appear if you try to send your non-anonymised balance.
Click on the 'Use Transparent Balance' on the bottom right of the Send tab to switch to your non-private balance. You should now be able to send them out.
