to get downloads try to increase the number of files you share you do this by going in tools, options, sharing and you'll figure how to add folders(click add and select a folder). you can also go in tools, options, downloads and check that your maximum downloads number is high put it at whatever you want as long as it's not 0

by increasing the files that you share you might get more uploads cause maybe you don't have popular files like you said. you should also go to tools, options, uploads, slots and make shure that you have more than 1 space for uploads.
