Hello, I know there are many, many posts about Windows Activation. However, I can't find this issue anywhere. MacBook Pro 2GHz, 2GB Mem. Parallels 3188, Windows XP Pro SP2 -- fully patched. I changed the networking configuration for Parallels, following which XP is now asking for reactivation. This isn't a particular problem -- except the activation window is blank as is the webpage for Microsoft. Please see the attached screen prints. Any suggestions? Has anyone experienced this issue? If so, has a resolution been found? Thank you, Peter.
