Its trying to block with right click instead of casting.
Here's how to do it: Create and setup the virtual disk: 1. It’s time to become Skyrim’s world heavyweight champion. Also includes scrolls and staves for the new spells. You'll still need dragon souls to unlock each stage of a Shout, but this cheat will act as though you have visited every Word Wall in Skyrim. What you have right now are some of the coolest looking spells I've seen. If the head turns dark, change the player weight to force the skin shader to update. Only 4 spells and I can already see this mod as being on par with Midas and Phenderix spells have to offer.
