I've been using Limewire for years, as it's the easiest P2P program I've found and usually returns good results. I've been updating over the years as newer versions came out, and have never had a problem until recently. I'm not sure which version I was running before the newest one came out, but I began to see trouble when I upgraded to the newer version of Basic (I think it said 4.14.8). The program took forever to actually start, then a long time (5 min or more) to connect, and everything seemed doggingly slow. I would click a tab for example, and sometimes have to wait 30 sec-1 min for the command to activate, and while it was open it slowed down any other programs that were running by a large percent, making things take double and triple the normal time to execute. I couldn't even close the program normally. I would exit it to system tray then go to exit from there, only it wouldn't allow it. I would have to manually exit the process from the Windows Task Manager (I'm using XP). I decided to give Frostwire a try, as it's basicly a copy of limewire, but as soon as I upgraded that version, I had the exact same prolems with it. I don't know if there's anything I can do to my system to make the new versions work. If not, I would be completely happy to go back to the last version I had that worked, but need a place to download it from. Any ideas?

*Edit* I found my old version (4.12.something) but am still curious as to why i would have so much trouble with the new one
