Hiya! Been "googleing" on the above subjects and came accross the forum, I refer to http://www.bleepingcomputer.com/forums/topic452034.html, which I can't find once in the site... I have exactly the same issue plus the APAgent.exe error....tried everything but cant fix it. Also noticed that quick play buttons on keyboard, such as play, pause, volume, etc, aren't working. Might it be related? Guess while cleaning up pc I deleted some files I shouldn´t since this issues started to hapen only after that. Have a HP pavilion and windows xp running. Can you help me, please?
