Repair Apple Application Support.

START/CONTROL PANEL/PROGRAMS N FEATURES/highlight AAS and click REPAIR

or you can try, installing newere version of iTunes.

it worked with me this way.

no need to un-install anything, just install the newer version over the old damaged one, probably it will work.

thanks it worked!

Great tip! I actually had to repair iTunes itself in addition to AAS to get it to work properly, but it seems okay now. Thanks.
