If the sync stops, check time and date setting, daylight saving also need to be correctly set.
If sync does not start, add nodes.

Press win + R
Type in: %appdata% and press enter.
Navigate to Raven folder

loc
Make a backup of wallet.dat, if you have not already.

Then move Raven folder to desktop.
Start wallet Raven-qt.exe, it should now open correctly and sync up.
Once it is synced up, quit wallet, wait for it to close down.
Now replace the fresh wallet.dat, with your backp/the one we have in Raven folder on the desktop from the step above.
Open wallet, if it does not work, you need to try a older backup of wallet.dat.
