I never had this issue before, even with this version. It's only recently when I tried resuming some files, it said 'waiting for sources' and it starts counting down 300 seconds which eventually leads to 'need more sources'. When I search for the file, there are plenty of users with the file but it still doesn't resume, whereas before, as soon as I searched for the file and there was a user available, my files would resume within seconds, or even if I didn't search for the file and I clicked on 'resume', my files would start downloading from where they left off. As I said, the incomplete files would be written in black, but now they're in red. I have no idea what is going on. I assume the red writing means the file is inactive or complete because when a file is complete, it goes red in the 'saved files' library.
