Can't click on food or potions

[Jackalep]

Just as I said above, clicking on a potion or food item (like sushi) just makes Deathspank run towards the bottom of the screen. I uninstalled/reinstalled and still have the same issue, does anyone else have this? There weren't any problems at all with the first two games.
