"I installed XP MCE".
What does that mean, installed on a new computer, or installed over another Operating System?
How did you install it, by re-formatting and installing from the CD, or by upgrading? Is this a genuine XP MCE CD?
XP Media Center uses "add ins", and this error message when Media Center is launched can show a problem with one of the add ins. So, I would start looking at those. This article may help;

I installed XP MCE and everything worked fine until i tried starting up Media Center and this Message popped out saying:
ehExtHost ? application has generated an exception that could not be handled.
Can somebody please tell me how to resolve this problem????!!!!
