Ok, thanks for that it clears things up a bit. If you are using v4.2 this is the problem. This version was not meant to be compatible with CS4. The latest available release for this tool at the time of this post is 4.5.3. This version should work in CS4 without issue. Please login to the site and visit your download center to obtain this latest release. You will need to uninstall the previous version before installing this newer one.
