It's so easy to load up the queue before pressing download if that's your issue. Just enter all the movies or episodes you want to download and then press download and go to sleep. Why people are downloading and searching at the same time is beyond me, what is that going to save you? I enter all the shows into the queue, yes changing providers, but not downloading as I search, that's the way the program works. I do not have this issue, I can search and download at the same time but if you do just add all your movies to the queue before pressing download. Think ahead.
I even download from 3 providers at the same time and nothing errors out.
