I am getting an error when I try to play a .wmv file in Media Player Classic saying:

Media Player Classic could not render some of the pins in the graph, you may not have the needed codecs or filters installed on the system.

The following pin(s) failed to find a connectable filter:
WMVideo Decoder DOM::out0

This same file will play in Windows Media Player ver. 10. I have tried to load the codec by uninstalling WMP 10 Re-booting and re-installing WMP 10. I can't install WMP 11 because that requires XP sp2. I have XP sp1. I have re-installed ACEMCP603PRO.exe .

Could someone please help me figure out how to fix this?

Thank you,
