I just got JRiver and updated my missing artwork - which took a long time (I have about 4,500 albums!!)
So then I left my computer on all night and it had about 35,000 updates to do (I can't remember the word JRiver used).
So now I start JRiver and the spinning beach ball is on and keeps going and going for over 2 hours.
Any idea how to stop this? Why this is happening?
