Now I'm truly stuck. Whereas when Vista asked to be reactivated before I could solve the issue by accessing the BC version of it through Parallels. This time round (and I don't know what has changed exactly) Vista wants to be reactivated in both Bootcamp native and the Parallels BC session. I'm staggered that Parallels sold me 4.0 on the basis I could run a Parallels session off BC when it plainly DOES NOT WORK. It also appears Microsoft are getting a fair share of inquiries about and displaying a distinct lack of interest... Are we Alpha testers? James, UK
