Does the new wallet reset coin age?  I updated from 2.0.3.1 and was actively staking (weight 7796) when I shut down the wallet.  When I brought up 2.0.4 just a minute later, my balance shows 0, with the entire balance is in the stake column, but the wallet says I am not staking because I do not have mature coins.  Since the balance is 0, with all of the coins listed under Stake, I can't do anything with the coins, either.
