Bug - Can't Register

I'm trying to register to enable my toolbar. When I attempt to register, I am receiving an error message:

" SeoTools Store Failed to register.
FileLoadException:Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)
Please try again."

Anyone know how to fix this so that I can register and start using the toolbar?
