Help please - Installation problems

[Cephaler]

First of all I´d like to thank all of you for being very helpful ( I´ve used the site and its features for years now )

Anyway...

I downloaded KRO 0618 via megaupload ( in 3 parts ).

I did put all 3 in the same folder, extracted the first one and got an .exe file.

It starts installing normally but once it reaches 35% ( when it´s installing data.grf ) it gives me a weird message and stops the installation.

I already checked the files ( their size in order to check if they were corrupted or not 1 - 500 mb 2 - 500 mb 3 - 391.500) and they seem perfectly fine..

I print screened: http://img689.imageshack.us/img689/6490/errorba.jpg


I have no idea what that means.. I already tried re extracting, downloading etc...

  I appreciate any attention / help.

( I might have posted this on a wrong section.. sorry if I did )
