Crashing of Window Media Player.

Last week I try to open a video with Window Media Player as always, then it send a message on my monitor - "Server execution failed". So I try to find some solution that worked, but I can't. Someone please help! I use Windows 7 Home Premium 64-bits. Advance thanks.

I had this error when i was playing multiple files in WMP,Play the file again and if it gives the same message try opening it with an another player,if you are getting an error on the other player too maybe your HDD have a bad sctor or your GPU transfer speed is slow as hell

This happened only in WMP, so now I'm using VLC instead of it and my laptop have never send me this message. So what I have to do in order to solve this problem? Sorry about my bad English, I have a fever today.

when using my desktop pc i get this message when i try to play another movie without closing wmp first,
it happens in wmc also.
its a fairly recent thing and doesnt happen on the laptop.
