Syncing and Connection problem


I hadn’t used my PIVX wallet (version 2.2.1) since June 2017. Now, when I opened it again it shows that I own 63.30 PIV but it will not sync. It got stack at block 801385.

In « wallet repair » there is no « delete local blockchain » button. So I had to go to the data directory and delete everything , except for backups, wallet.dat, pivx.conf and mastermode.conf

After all this, when I restart my wallet it still won’t sync, the red icon says : 0 active connection and the balance says.: 0.00 PIV available. I am on Window 7.

Help would be greatly appreciated.
