For some reason when installing the game it works at the start but when it asks for the second file to install it is unable to recognize that its there, i've re downloaded all the files and made sure they are all in the right place and its still not working.

Any ideas guys?

You ever get this installed? Sounds like the second file is incomplete/corrupt or else has the wrong filename, e.g. added "(1)" to the name. Try downloading it again including the setup.exe with all files in the same folder.
