How to fix Runtime Error 21 from FaceBook?

Asked By ryan butler 20 points N/A Posted on - 07/28/2011

I am using Windows Vista. I am having an error from which I think I got from using Facebook after clicking a link shared on my wall then redirect me to a webpage that I have no interest of. When I was about to leave the site, I got this pop up message stating:

Runtime Error 21 at 00DC49D2

After clicking the OK button below, another window opens with,

C: Windowssystem32splmncsjapi32.exe.

My desktop icons disappears and the error keeps popping. I need help. What do I need to resolve this?
