Delete all the files (in %appdata%/XIOS/ for windows, /home/user/.XIOS for linux) except XIOS.conf, masternode.conf and wallet.dat
Then, copy/paste the files from the archive and restart the wallet.
If your coin balance is wrong, type "repairwallet" in the debug console and restart the wallet.

There are now (2) block explorers, both on the correct chain (working with Yobit).
Both are syncing as of 10AM PST, but, you should able to search transactions/address' up to the latest block.
