I am having the same problem. Limewire started freezing when booting up several days (of successful use) after my OS 9.0 to 9.2.1 upgrade so I tried to re-install from the original install file that I saved in my limewire folder. It was originally successful a week ago with no problems. That gave me the corrupt message. I then downloaded it again from Limewire and got the corrupt message. Same with download from Gnutella site. Running OS 9.2.1 on iMac 500mhz with MRJ 2.2.5
