I need some insight..the wallet I have I got from diamondcoin.net (I did this over the weekend). Since then, I've seen where every thing has been revamped. The wallet I have I can't unlock it  using walletpassphrase "passcode" 9999999 true. In the "settings" there isn't an option to "unlock". I want to start POS. Then I read as long as you dont POS you're collecting coinage. Help me to understand what is going on.

do i need a new wallet?
