Setup File expired File is corrupt from transfer

[Strobe]

The title says it all I have had limewire for awhile and I have version 4.14.10 and here is my problem when I download songs it works fine and plays fine too, but when I restart my computer and goto limewire it loads up then when I goto my library all the songs are gone and they are in the programs folder??? Also when I try to click on my songs they will not play at all...this is what limewire says in the message "ERROR limewire will not launch the specified file for security reasons" does anyone know whats going on I have uninstalled it and reinstalled it twice and it seems to be doing the same thing PLEASE HELP

Have the file extensions changed to .zip or.exe?? If so then you might have a worm or virus.
