I've never used a more crashy, noisy, unusable piece of software, when I think of the hours I've wasted so far trying to get this to at least work... I am not having a positive customer experience.
Have you updated Windows last time?
Seems that there is running a service in the background...
I have had the Disk Indexer (windows service) running after updating windows.
This service was scanning the HDD every time and there was the same effect you had...
Let your pc run over night then the disk indexing is ready.
