Hi Mathew, Welcome to the I-Novae Forums
You’ll need to make sure the email you used on Kickstarter is the same as the one you used to create your account here. If you used another email address, you can add it in your account preferences.
Check out the Beta Weekend thread for all the details, it should answer most questions.
If you still have questions, or run into problems during the process, let us know and we’ll assist as soon as we’re able to.
