Hi AdrianR,
Regretfully, Microsoft DreamSpark is only available to those actively enrolled in some form of educational institution.
Taken directly from the DreamSpark FAQ:
What is DreamSpark?
Other than totally cool? Glad you asked. Here’s how it works: if you’re a current university or college student, you can download professional Microsoft developer, designer, and gaming tools through DreamSpark at no charge.
