If you only opened the wallet for a few seconds, that will explain the lack of connections. Open it and leave it open. The only way for you to have lost your coins is if you deleted your wallet.dat If you did, look in your recycle bin and if you deleted it from there too, they're pretty much gone forever. If you've just downloaded a new wallet, find the old one and replace the wallet data.
I downloaded and opened judgecoin-qt-v1.1.2 on another computer, then i closed judgecoin-qt. Then i copied wallet.dat from my first computer and past in C:\Users\UserName\AppData\Roaming\judgecoin.
Then i opened judgecoin-qt-v1.1.2 and i can see all my transaction, but i dont have connection and my balance is "0" and in "transaction status" i see: Generated but not accepted(mined) or conflicted(received with pool), any help?
