I use a AMD AthlonPC with 256 MB RAM and i recently bought a new Hitachi 80 GB hard disk. I have two OS Win 98 and XP. All my programs are installed in XP and sometimes when i try to open MP3 files it is not opened with any program. When i try open with.. extension all the installed programs like Winamp, ACDSee, Acrobat Reader, Power DVD etc. are shown by the name Service Manager in the open with menu. This happens all the time aven after i have checked the "always use this program for opening this kind of files". Somebody please help me. I have already tried formatting the disk and istalling the OS and Software again.
