TACX Desktop App lost a workout ?

I did a RLV workout (Amsterdam City) and about 3/4 of the way through I lost internet. Film was downloaded so only issue is that I lost satellite view so no real problem. At the end I clicked to save it as usual and all seemed OK ...except it's nowhere to be found. Shouldn't it still save the workout locally so lack of internet and access to cloud shouldn't affect it?
Does anyone know where the file might be stored locally and how to get TDA to recognize it again?
