Virus control panel in Daw

Hi having a bit of trouble using my virus with ableton, i was wondering why after using the virus and saving a certain song in ableton and then coming back to it later, the virus connects fine and plays what was saved but has no virus control panel comes up
This only happens when i reopen a saved song with the virus being used within that song
How do i get the control panel to reappear ???
\Thanks loads for any help

Thanks thought it might have been that simple
