plesk invalid pointer (COM Error 80004003)

I was running the Plesk reconfigure tool, to modify the IP address for the virtual hosts to a different one when I ran into the following error:

Unable to execute "C:\Program Files\Parallels\Plesk\admin\bin\websrvmng.exe" --change-ip-address --old-ip-address=10.20.44.14 --new-ip-address=10.20.44.14:
Invalid pointer (COM Error 80004003) at execute console command --change-ip-address

After doing some debugging, I found out that the following registry key is the culprit for the error:

HKEY_LOCAL_MACHINE\SOFTWARE\PLESK\PSA Config\Config\SitesCache

I removed the key (trust but, always backup), and then re-ran the Plesk tool. It resolved the issue! I still think Plesk is a miserable piece of code!
