Authorization problem

[tarch]

I have entered wrong serial number based on which was generated request code with word 'foul' at the end. Each time I start Revit (licence expired) I am forced to get into activation page where I have no option to change serial number.
What is the way out?

Thanks

I had a similar problem.

You can change the serial number via
Help->About Revit Architecture 2009->Product Information->Update button.

Even then it took me a few attempts to activate successfully - probably needed a reboot.

Hope that helps.

Thanks William, it worked.
