Hi all, I've recently downloaded and installed Winamp 5.31 and now I can't play a mp4 file I had saved (it has the .m4a extension). I went into preferences with Ctrl+p but I can't work it out. In the treeview I'm on file types, but when I tab to associated file types it keeps saying "no selected item" whenever I move up or down the list even though Jaws will say the different file types in the list. Even when I've pressed the spacebar on all file types and then closed the dialog, the file won't play when I open it. Any assistance would be greatly appreciated. Regards Vivien
