and because of providing that, we now know that you're not running the current Winamp release and that there's 2 3rd party plug-ins in your install:
Audioscrobbler Winamp Plug-in ml_wa2_scrobbler.dll 2.1.0.9 274 KB
Unknown General Purpose Plug-in gen_plsave.dll - 6 KB
so, re-download and re-run the Winamp installer from
http://forums.winamp.com/showthread....74929#download (use the .co.uk link).
then also remove the two plug-in dlls (ml_wa2_scrobbler.dll and gen_plsave.dll) from your Winamp\Plugins folder (either rename them to have a .off extension or just move them out of the folder completely) and see if that resolves things along with using the current patched Winamp installer.
