Did you just upgrade to v2? If so and you have the old woocommerce themes in your custom theme directory, that could be causing the problem. Remove them (or temporarily rename the directory)to see if it fixes the problem.
V2.0.2 uses a different theme structure than anything under v2. If removing the woocommerce themes from your custom fixes the problem, then copy the new woocommerce themes to your custom theme directory, and all should be good. Of course, if you made any customizations to those files, you'll need to do them again.
