I unplugged my system with out a shut down now i get a message that says MSACM32.dll not found. also my sound from internet sound is gone, my volume control in my start tray is gone. i think it has to do with my 32bit audio compresor. any help i have tried every thing on the trouble shooter and no luck

If you are running Win XP try restoring to a point when it was working.
Here's a link where to find system restore and other options for repairing this file.
