WPC Product Bundles cart issue

I have an issue with the WPC Product Bundle plugin. After having set one bundle up, I tested it, but it appears that once you punch “Tilf?j til kurv” (Add to cart), the plugin refuses and tells the buyer: “Du kan ikke tilf?je denne pakke til din kurven” (you can’t add this product to the cart) shown right above the product image. What have I missed? Is this a bug? Has it not been tested thoroughly with the new version of Woocommerce? Or will it only work the second I buy this plugin? I would love some feedback. ??
