PopCap sent me the following fix and it worked.

Thank you for contacting PopCap Games Customer Support.

We apologize for the persistent error regarding your game's registration. In order to resolve this, we recommend deleting the following three files from your C:\WINDOWS directory:

popcreg.dat

popcinfo.dat

popcinfot.dat

These files are all related to PopCap Games registration processes, so their removal should allow you to reregister your game successfully.

If the OS is Windows 7, the files may be in a different location:

c:\ProgramData\PopCap Games\popcinfot.dat

c:\ProgramData\PopCap Games\popcreg.dat

In order to access these files, you may need to set your Folder Options to allow you to view the directories that are hidden by default. To do so, please follow the steps below:

1. Click the Windows ("Start") button in the left corner 2. Click Control Panel 3. If your Control Panel is set to Category view, change View by option to Large Icons 4. Click Folder Options 5. Click the View tab 6. Click Show hidden files and folders 7. Click OK
