Is it on windows?  

Go to c:\users\your_username\appdata\roaming\darkcoin
Create a text file and save it to that folder as "darkcoin.conf"
Open the file in notepad and type "addnode=23.23.186.131" then on the next line type "addnode=93.95.228.131"
Hit save and re-launch the wallet

The first node is the official node, the 2nd is one of my masternodes.  I was having the same problem the last couple days.  Adding my masternode caused it to start syncing immediately.
