I'm not sure if the solution suggested worked for the topic starter. However, I have the same problem and I checked out the link that should provide the hotfix. However, it doesn't say anywhere where this can be downloaded from. I googled the name of the zip file and it doesn't return any hits. Any useful advice - that avoids the need of re-installing and reregistering - would be most welcome!
pietervertaler, you can find the zip files in the link provided up here. When follow the link, on the right side of the page are the zip files that are stated in that article. I didn't try them myself but I hope this will be of some help for you.
