Ok so I backed up the dat and downloaded your link, no wallet in there.
Where do I put the dat, newest version is not working
In windows, put it in the user\username\appdata\roaming\shacoin folder. In linux, home/username/.shacoin
Make sure that it, your shacoin.conf file, and wallet.dat are the only files or directories in there. Then start the wallet. It'll automatically sync to that file and create the others.
Another trick that sometimes speeds things up is to not put wallet.dat in there, but rather have it backed up until the wallet is fully synced with a new wallet file. Then delete the newly formed wallet.dat and put your original in, restart the wallet and it should all be good.
