Try this on the computer you used to send the coins:
- Close wallet
- Backup your Einsteinium folder from %APPDATA% to a safe location - VERY IMPORTANT
- Delete everything except wallet.dat from %APPDATA%\Einsteinium
- Open the wallet and wait for it to sync
If you are using Windows, just press WIN+R and type %APPDATA% in the window to get to that folder.
If something goes wrong, restore the folder you have from backup.
