Just updated to 4.12.3
Before I did, my Limewire had been working, but as I ran the installer for 12.3, the installer froze after a few seconds, and LW stopped working. so I downloaded Limewire from the Second option on the site, and installed it.

For some reason, I disabled Connect on startup, but as I started LW, the files I was downloading started to download.
When I connect, the five bars all lit up green, and there is still a wall of bricks beside the globe.
Hopefully, this works for a long time, and not a few minutes like the rest of the time.
