Windows Media Player 11 Unable to start

I have windows Media Player 11 and since yesterday every time that I try
to use it after I start IE7 stop working WMP11 I try to fix it. I try
the following
- Click *Start*, click *Run*, type regsvr32 jscript.dll, and then
click *OK*.
- Click *Start*, click *Run*, type regsvr32 vbscript.dll, and then
click *OK*.
And every time it just pop up a window saying
DllRegisterServer failed with error code 0x80004005
and I have look on a couple web sites but I can't find something
specific about WMP11. Can somebody help me.
