After this a new window opened saying "Problem! My signature check fails on the installed FSUIPC4.DLL. Please check that I am not listed as an "untrusted publiher" in INternet Explorer (Internet Options-Content-Publishers)." I have checked and deleted everyone of the untrusted publishers tab, and this message still shows up. I've talked to some other people and they have never seen or heard of this problem.
