Well, THAT'S ME.
I've been using LimeWire on my Windows XP since about June.
I have the FREE version because I'm too scared to ask my parents if I could buy it.

Things were PERFECTLY FINE until about August or September.
Out of NOWHERE the program stopped connecting,downloading,uploading,sharing ect.
So I figured, what the hay, I'll just un-install it and re install it to see if it fixes itself.
NEVER DID.
So I got furious and deleted it.
I haven't had it SINCE until about 10 minutes ago.
So I went through the WHOLE process again.
The program came up.
YEY CONNECTED!
Boo no downloading success.
So not ONLY am I extremely enraged, but I have NO IDEA why it's not working.
I checked the DOWNLOAD VERSION, Java Versions. All that.
ANY HELP?!
