Be patient while your wallet finds connections usually is the fix. I helped someone with their wallet just yesterday and it took almost an hour to find the first connection. Poor internet bandwidth was likely the culpret as they had many wallets and active programs hogging available bandwidth.
You can try to speed this up also: From the debug console, issue "addnode seed1.sterlingcoin.org.uk add"
You can do this for seed2.sterlingcoin.org.uk also.
The OP has additional public seeds community members have provided also. You may want to review that info.
I hope this helps!
