Unity3/iPhone won't accept my serial?

While trying to register the Unity 3 preview, I have entered my Unity iPhone serial (which, I’ve confirmed on the store page, is valid for the Unity 3 preview). It goes through the whole process and appears to work fine until after the registration box disappears and then a dialog box appears that says:
“This version of Unity cannot be activated with a free or trial license”

I think I’ve ruled out my license not being legitimately able to activate U3 so I’m leaning towards a technical bug. Any ideas?

b2 or b3? This was a known bug in b2 that was fixed in b3.

Whoops, that was b2. Just found the b3 link in the -other- email I got. Thanks much. :slight_smile:

If it worked then glad I could help :wink:
