I took the test drive with CS5, decided to lose it and continue using CS4 and now it will not allow me to administer the site. I tried uninstalling both programs and running the creative suite cleaner to no avail. Once I reinstalled CS4 I got the same error message. Any ideas?
Once you had Administer in the latest version, you can't Administer in older version of Contribute. Please refer to the blog post, http://blogs.adobe.com/contribute/2009/09/compatibilty_transition_mode .html.
If you like to continue with older version of Contribute, then you have to remove the Administration using the CS5 and reconnect to the site using CS4 and enable Administration.
Note:- All the Adminitration settings, role settings and roles will be lost.
