I had a feeling you were going to say that... I read them. It says after you run the upgrade to:
New plugins included in download.
In the install directory set permissions on the file product_pppro.xml, source-vb4.xml and source-vb42.xml files to 777
2. Go to your photopost admin panel and hit the option to generate vbulletin plugin xml.
Umm.... how can I go to my admin panel if I don't have a link? I don't know what the direct URL to it is. I always get to it by that link on the page.
