I had installed the latest version of Iconpackager (Version 3). After I did so, my Pinnacle Studio refused to work. At first I thought the problem was with Pinnacle, so I uninstalled and reinstalled it again, with the same results, it would give me an error message stating that it failed to initialize. I then realized that the only difference from before and now was this update, so I reverted back to version 2.99 and viola, Pinnacle works again. Also, another issue was that I couldn't drag icons into or out of the tabs in Objectdock plus, which was also resolved once I reverted to the previous version. I'm hesitant to install the latest version, at least until I know that these issues have been resolved. I use Pinnacle Studio so not using it is not an option for me.
