Maybe? you should open the 39546 port to get more connections.

If it doesn't work try to repeat this message:
"I made a backup of my wallet, uninstalled litecoin client, deleted the appdata/litecoin folder, downloaded the zip file of client, extracted, started it back up, closed it, changed out the wallet.dat in the appdata/litecoin folder with mine, restarted client and now it's downloading.."
