It started happening a few updates ago and I can't figure out if it's some setting that changed or if there's some reason it can't access the file. Has anyone else had this problem and been able to fix it?
I'd like to avoid a blanket uninstall/reinstall and actually figure out how to fix it so I can avoid it in the future.
The PC it's on is running Windows Vista Business x64 if that makes a difference. Winamp is version 5.572 (x86).
Update: I just checked and Winamp.m3u is getting saved properly on close, but not loaded properly on open.
Update #2: screenshots of playlist association settings:
winamp.exe "%APPDATA%\Winamp\Winamp.m3u"
