after installing windows media player 10 on
my PC, SFP shuts off after about 5 minutes.
the error message was no Midiclock and much more "exceptions".
After deleting wdfmgr.exe in C/user/windows/
system 32 the problem didn't occur anymore.
(wdfmgr.exe comes with wmp 10 and starts in
about 5 minutes after windows start.It has to
synchronize some wmp applications).
Maybe this will help somebody
