Thanks to Djoser on Bitcointalk I just installed Gridcoin mandatory update 3.7.8.0 Mac Version as I'm using it on Mac, but as always all the latest wallet downloads you can find here: http://www.gridcoin.us/index.htm#Downloads
Bitcointalk GRC Thread I'm checking and contributing there all the time. If you are on Bitcointalk - I suggest you to visit and communicate there too, as it also helps in marketing and promotion of Gridcoin.
So finally after more than a month of problems with my wallet I'm back and everything works fine!
I lost some GRC which I received (probably mistakenly by staking) but I got GRC from Boinc!
To celebrate this I'm willing to give 10 GRC for new Gridcoin users (1 GRC per person)
And another 10 GRC for new users on Bitcointalk (1 GRC per person)
I won't be checking if you are new user or not - you can just leave your wallet here, but if you are existing user - probably you won't need 1 GRC as you probably have much more Gridcoins.
The purpose of this is to attract more users to Gridcoin
