The WPF/E Installed on your system is no longer valid. Please go to Microsoft's web-site for the latest version

I started getting this when I got home tonight:


and this is painful since I need to finish my INETA presentation for Saturday. Thinking possibly the download I had was corrupted, I re-downloaded and got the same message, but in the process saw the message that the code would be good until February 18th.

I played around and found if I set the date back to January 30, it works fine, but setting it forward to February 1 it throws the error. I get the same results with Firefox and IE7.

I ratted around and found this on the WPF/E forum at Microsoft

According to Mark Rideout a Microsoft Program Manager, "This is a result of a bug in our timebombing code (only affects Windows OS). You'll need to reset your clock to continue using WPF/E. We are working on getting an update out as soon as possible."

Fun, fun...

I had the same problem. This solution works for me.

1. Uninstall Silverlight
2. Reboot
3. Download and Install Silverlight Release Candidate 1.0
4. Reinstall Silverlight 1.1 Alpha Refresh. It will prompt that Silverlight has been installed, but the error message is gone.
