I also can get nothing to download, but my message is different. It always says "waiting XXs for 1busy". Then when it gets down to zero seconds it starts over at 60.

What I have tried:
1) Varying the connections, and the approximate number to keep.
2) Disconnecting and reconnecting.
3) Disconnecting every other network connection I use.
4) Both enabling and disabling ultrapeer capabilities
5) Making my shared folder really big to see if I'm being denied for connection preferencing or freeloading (which I seriously doubt, but thought I'd try anyway.)
6) Even rebooting!

I am running 2.2.3 on a linux box with Java 1.4.0. My connection is plenty good, cable with which I have peaked at about 500kbs. I doubt my ISP has refused the appropriate port connections because I have, in three days, been able to download ONE file, a small mp3 that took 30 minutes. That is, unless they block most but not all.

I'm wondering if my problem is external to my system and ISP.
