I believe my Opsrey 230 card worked with Adobe Connect 9.00 addin, but only shows black with the 9.03 addin. How can I get an old copy of the addin?
Older versions of the Connect Add-in can be found here: http://www.adobe.com/support/connect/downloads-updates.html
However, there has been only one version of the Add-in for Connect 9. The version you are referring to is the version of the Connect software on the server. If you are hosted, then there is not the ability to revert back to an older version of the software. If you are licensed, then you should be able to revert back to a previous version.
