I got similiar problem it didn't unzip properly...
I downloaded from second uk site on the list and got it right...
think u should try again

I got winzip 8.1 so that was not the problem...
I downloaded it for 4th time from uk server and got it unzipped and installed and now it works...

Still don't know what the problem was though...

thanks anyway

I downloaded full 7.1 version and when unzipping with winzip it stops at 7% and gives error wz51 or something like that...

i downloaded it 3 times from different places so what to do now?
