No audio in playback

I recently upgraded my HDD to a SSD no license problems at all. All my projects except one are fine. When I load the one exception I get no audio. All my audio settings are good, drivers, interface, studio setup etc. and active. I see the meters moving when I play the tracks but no sound. When I edit the instrument and play on my controller the meter moves and still no sound. All solo buttons are on, no muting whatsoever. I even exported an audio mixdown which had no sound as well. The project was before I upgraded from elements 11 to artist 12 but it was fine until I did the SSD upgrade. You help is greatly appreciated.

I forgot to mention the project in question is on an external drive not the HHD I upgraded. Thanks
