You're lucky it's half time.
2a. Browse to C:\Users\UserName\AppData\Roaming\BitShares X\wallets\.backups\
2b. Copy & paste the 'default' into the following directory: C:\Users\UserName\AppData\Roaming\BitShares X\wallets\
^ Note: replace UserName with your Windows user name; AppData is a hidden folder so you need to type it in manually or turn on the viewing of hidden files and folders ^
2c. Windows will ask if you are sure you want to replace the existing folder & files, select yes.
2d. Open the BitsharesX client and your wallet should be restored. You will likely need to re-scan the block chain using 'wallet_rescan_blockchain' to pick up any transactions you have made/received since the last time your wallet was automatically backed up.
If this works, make sure to back up your wallet using the other method just in case for future use: https://bitsharestalk.org/index.php?topic=7768.0
