I got my PC reformatted last week, the technician put a newer version of LW, and since then, I cannot dowload songs from limewire. The signal bars at the bottom is red and it says 'connecting' but there are no search results shown, nothing, just nothing until it's done.

Try the fixes here: If LW Will Not Connect

If nothing helps, post back with your system details. That thread has info about the details, so do the forum rules which you had to read before posting. Without those details, we can't give you any more help.

Thanks Birdy,

I've tried to disconnect and then connect, I've also tried to remove my gnutella and replaced it with a downloaded file a while ago, but still it won't connect. I have a 4.8.1 version of LW. My former version which is an older one works just fine for me. Do you think I have to reinstall it again on my windows XP? And if so, where can I find or download the older version of LW?

Since you won't provide your system details, we can't help you any more.

Good luck with your LimeWire.
