i have just found a fix for the connection problems!!! first, dlete all versions of limewire on your computer, be sure to check for hidden files (could be stored under roaming) and delete those too. once you have removed limewire completely, go to
Download LimeWire, LimeWire 4.16.3 Download where you can download version 4.16.3 of limewire. once you download it, your bars will go from one to five and your connection will be very strong. hope this helps cuz it worked for me
