Lego star wars 2 installing problem ?

I just downloaded this game of ares.Every time I try to install Lego Star Wars 2, a window appears saying "Error 1330. A file that is required cannot be installed because the cabinet file E:\Defaul~1.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt. Error 3 was returned by WinVerifyTrust." Has this problem happened to anyone else? Can you please give me some suggestions? I really really want to play.
