I've had great success lately since getting Newtella workin', but will you all please either put in-complete downloads in a separate folder or delete them. It's useless downloading a 5 meg file if it's incomplete!
Also set your max downloads to whats happening otherwise your machine will keeep tryin' to connect to files that you've checked before! If you can only take 2 at a time, set it to that, it makes it harder for you and everyone if you set it to some rediculous number that you already know your machine won't handle!
