I just upgraded my Limewire 5.4.6 to 5.5.5. Now several of the headers are missing, including Bitrate. How do I get the headers back?

On the search page, select which category you want (eg audio, video etc) from the sidebar.

Now right click on the column header & you'll see a dropdown list of column options - select the columns that you want to see, by clicking. To remove a column, just click on it again to unselect (so that there's no tick beside it) from that list.

OK! I closed Limewire, then opened it again and voila! there were all the headers. Thanks for your response.
