I'm assuming "fonts" means "sources".
Try a local search for the file. Are there sources? Try a global search. If there are few or no results from a local search and significantly more from a global search, try switching servers. If there are few results from even the global search, then you may have to switch servers a lot to find the ones where the sources are. If there are no results, then your file just isn't available in the ed2k network.
If you have enabled IP filtering, check your log to see if sources are being filtered.
The strange circle is an indicator that you have "expanded" the file by double-clicking on it. If there were sources available, they would be showing in the list below the file. To make it go away, just double-click the file again.
