I opened a project using the shift key/safe load mode to work on some audio segments, not having my outboard disk with all my samples on it. 
On returning home I  transferred the newer .cwp file to my desktop, overwriting the original.
Now when I open the project the synths appear to load the various samples but they are "greyed" out in the browser and I cannot get any sound generated by the synths.
Audio tracks are fine.
 
I tried opening the file again using the shift key/safe load mode and answering "Yes" to the load synth dialog but with the same result.
I tried right click the synth in the browser thinking the context menu might give me a choice-no possible reactivation selection however
Any ideas on how to get these synths (TTS and Aria in this instance) loaded correctly?

Thanks,

 The fix is in the Browser Synth drop down menu "Synth connected" choice
