loading user interface.......
 

I just recently purchased Limewire pro, and I seem to be having problems starting it, whenever I choose to start it sits there on the loading user interface screen, I was using basic awhile back and I didnt have this problem I noticed it just recently started happening. Any suggestions?

Try deleting your LW Preferences folder whilst LW is closed; instructions here: Fixes for Limewire

Did all of those, and it still sits on the same cscreen

anymore suggestions

seems to be taking up all my CPU space

Uninstall & re-install Java. Downld the Java installer & save to your computer & then install it (don't install Java over the net.) You can use my link above to get Java. There is a more recent update but versions 1.4.2 & 1.5 update 1 are there. If you still have the older LW on your computer it might be wise to remove it. When you open LW Pro, use the Control-Alt-Delete keys & see how many times Limewire is listed. If it's listed more than once then you have a problem & should remove the older one. Need to kill their activity 1st before removing.
