"Could not verify the integrity of the installer." for high end loft. [SOLVED]

hello i'm having issues with the High end loft stuff installer. At first it wouldn't open at all then i unrar it using stuffit spander and it opens but it gives me the "Could not verify the integrity of the installer" message. I see there are other people having this issue in other expansions so i started a thread to see if anyone has this issue resolved or to see if anyone can help me soave it.

thank you

//EDIT

I just finish downloading the late night expansion and the installer is doing the samething.

//EDIT

thank you.
