HOW can I make my Wallet QT to sync up?

I downloaded the Wallet. It is just the .exe file. I double click on it and the QT opens,but it is permanently showing "No block source available" 4 days behind.
I created a particle.conf file in AppData/Roaming/Particle with the following lines in it:
testnet=0
listen=1
maxconnections=100
server=1
daemon=1
rpcuser=user
rpcpassword=pass
rpcport=8776
rpcallowip=127.0.0.1
Restarted the wallet several times!
But it is still not syncing up!!!
PLEASE HELP!
Did you try installing wallet on another computer? Like I answered you before, if you are having a miner on the same computer, I have experienced similar problems (I had those problems with GUI Miner and Litecoin wallet, but I believe they are pretty much the same).
And if you have other wallets on same computer, are they working? If not (and even if they are), check your firewall settings to make sure your firewall isn't the problem.
