I also get the same message since updating. "Loading User Interface" I left it on for 2 hours to see if it needed time to start up and it never moved from that message. I also brang the task manager up to see if I could end the program but it wasn't in the box of programs running. So it stays on the desktop and I have to shut my PC down to clear it. Limewire worked perfectly before I updated.

2. i don't have windows firewall activated, but i do have Mcaffe firewall which says Limewire has been allowed to access the net.
