I have a message "Internal Server Error" blocking my screen. How do I get rid of this?

I have a notice blocking my screen: “Internal Server Error Call to undefined function mcrypt_module_open ()” What does this mean and how do I get this thing off my screen?? My torrents are downloading, but I can’t see them because of this hunk of junk filling my screen!! PLEASE HELP!! And I mean soonest!! I’ve never seen one of these before…

That’s not a BitComet error. Presuming you’re using Windows, I’d uninstall mcrypt as that doesn’t install properly most times.

mcrypt is often installed along with xampp or apache. Che ck for anything that you recently installed to see what nay have importewd it
