    Extension Manager cannot install .XZP File. Why?

    EdwurdAdam Level 1

      I have downloaded a set of Transitions from Filmimpact.net for Premiere Pro CS 5.5. It is a .XZP File


      I Double clicked on it and Adobe Extension Manager CS 5.5 opened up.


      I accepted the License agreement and it opend up.


      I went to install These transitions and I get the following Message


      "The Extension 'Transition Pack 1' does not contain valid signature. The extension will not be installed."


      What does this mean and how can I fix it?


      I want to install these Transitions in Premiere Pro CS 5.5?


      Thanks in advance
