For me, this problem is now resolved!! A guy just posted the clear answer in another link that I had started 3 months ago.

Now I use MS Windows, so this isnt the answer for mac people.

HE showed how I could search for the Display.props file, which is found in a directory on my computer (which also contains a file called limewire.props). And my Display.props was BLANK. If yours is blank, missing, or corrupted, then simply put the information in it. An example of what you could put is below. (just make sure to shutdown limewire before creating or editing the file, save it, then restart limewire to get it working again.)

Example Display.props code:

LOCATION=105
COUNT=15
QUALITY=67
TYPE=37
VENDOR=60
SIZE=67
CHAT=28
audios__audio__bitrate__=59
SPEED=57
NAME=393

Good luck!!
