People, 
a snap shot which took place today is a scheduled activity in transition V2 to V3. After V3 becomes active on 15th, there s no point keeping V2 (old wallets) online since any minted or mined blocks will not be transferred to V3 chain. Please be patient for these last 36 hours or so until we get V3 version active. 
Again, everything goes as planned ATM. 
little correction
not after 15th
already now all DMDv2 wallets should be closed
the snapshot was the end of DMDv2 
DMDv3 will open gates public on 15th
