Same for me, wallet open for 48h, with nearly 10k coins on it, no way the staking is working,
Any reason why?

We're going to issue a mandatory wallet update in approximately 24 hours -- at 6PM Eastern time tomorrow. We'll be upgrading all the seed nodes of course, and we've confirmed the wallet update with both Bittrex and Poloniex. Please be sure to upgrade!

Countdown: http://www.timeanddate.com/countdown/generic?iso=20140602T18&p0=179&msg=MastiffCoin+Mandatory+Wallet+Update&csz=1

We would generally prefer to provide more notice for a mandatory wallet update, but the blockchain has been quite slow and we know that a lot of you would love to see those fast MastiffCoin transfer times you're used to again.

We're reducing the maturity time for mined blocks to 50 confirmations, and cutting the minimum stake age to 6 hours. Also, we're implementing a few simple fixes for small bugs that have been recently patched in Bitcoin and Blackcoin.

@madjules007 seattletu The minimum stake age (time the coins must be in your wallet) is 12 hours, and then you have to wait for them to stake. It isn't guaranteed after 12 hours.. there is variability, and it will depend on coin age and number of coins (your "weight", vs the network's weight).

Great Devs! Keeping the network running faster with such a quick mandatory wallet update is good thinking.
Keep up the good work.
