Back up your wallet.dat or dump private keys via console in wallet . Most important. Allways make backup
Step two
Pls use standard windows wallet without bitspace.conf.
Just use links in OP or on website.
From start it looks like there is 0-1 connection. Let it run few minutes. It will resynch and your connections will start to appear.
Step three (for those who have wallet already installed and cannot sync)
(If you run wallet with bitspace.conf in the past...you have to (!!!! NOT WALLET.DAT !!!!) erase all files in folder bitspace (appdata/roaming/bitspace)
