I paid my membership to upgrade to 4.0.6 a long time ago, well over a year. That has nothing to do with why my song list was erased and the complete program, including the installer.
The program was showing a warning box claiming problems, and then t erased my entire collection. Fortunately I had everything except the downloads from last week saved on disks.
I have upgraded my membership to Limwire and the files did not return, in fact, limewire erased my 3.0 series and all those files, in order to upgrade my program.
Go explain that.
