I have a similar problem. It is most likely that you're downloading files with a low score (i.e., 1 or 2). Xolox works very well with high score files, but sometimes it takes a while to download files with a low score. I have to wait several days sometimes for rare files. If those 1 or 2 users don't stay on for very long or don't have a dedicated connection (cable or dsl), then you will have trouble getting those. I'd recommend you look for higher scores, or just wait a few days. It just takes time.
