Invalid serial number of what? The game code in Uplay?
It looks like the game is attached to your account properly. Please completely uninstall the Uplay client from your PC, then download and install a fresh version from uplay.com. Then, try launching the game as normal. If it still doesn't let you access the game, let us know.
