Problem with the download(or install)...

[Havok.]

Hello ,
I recently re-downloaded this amazing mod and tried to install,but every time it says that something different is corrupt,one time its some Barbarian file and one time its the Roman battle theme song...
I've re-downloaded the game for 3 times and it still won't work and say that some files are corrupt,I don't remember that this happened to me before as well.
What can I do to solve this ?

I have no idea about why that is happening to you mate, try downloading again from different sources
