There could be many reasons your files aren't being uploaded, but there are some check you can make.
The first is to see if your setup allows "incoming connections" (which are different from the stats in the connections pane).
In your preferences, go to the Bug Reports and click the button for "Sample Bug Report"
Scroll through the display until you can find the line about "accept incoming this session=true [or false]"
If it says false, post back with your specs, especially how your machine is wired to the internet, and we can go from there.
If true,
, post the name of one of your files and we can try to confirm that it can be found and downloaded.
Cheers
