I am in the same boat except my wallet is up to date and 7.1.0. Im on ubuntux64 and the wallet wont even start the sync with 8 connections on the BC network. The process is not throwing any errors and the machine I'm on is fully functional. I have cleaned the bitcoin directory twice and rebooted twice as well. I am connected to the Internet as I am still trying to connect as I type this. As of right now after running for several hours, sync is at 0 of 207028 blocks with 8 connections.

Restart OS, restart Bitcoin, try forwarding port 8333 on your router to your machine. If there is no progress after that, you might consider deleting all the files in your [Bitcoin data folder](https://en.bitcoin.it/wiki/Data_directory) **except wallet.dat** (if you have made any transactions, deleting `wallet.dat` will make you lose your Bitcoins). If you just want to use Bitcoins casually, or don't want to wait for the client to sync, you can consider using an [eWallet](https://en.bitcoin.it/wiki/Category:EWallets).
