Do you see:
"Wallet Loaded successfully"
"Connected to Bitcoin Network successfully"
"Synchronised"
"Your wallet is ready to use"
Is it fully sync'd? Can you see in the bottom right corner if it says "Peers: 10" and has a green light?
Also, go into the your %appdata%/MultiBitHD/logs directory and look in the multibit-hd.log file for any error messages.
Only first two were checked and that is it, nothing happened afterwards. No peers or even the value showed up, but the amount of bitcoin showed up on the screen behind.
So after many attempts to restoring the existing wallet which failed, I restored it all from the keys again and then it worked fine afterwards. So its solved now.
