error when extract kRO files..

[mauiii]

I've downloaded all the 12 files..
some of the files are ok but the 7 files (part 1 - part 7) are corrupted..i've use winrar and 7zip..
both said the same thing..so I redownload all the 7 files again..but still got the same answer..( rdata.grf is error ) something like this..
i'm really getting frustrated by this kind of things..pls help me..i beg u.. 

in the other hand i've downloaded an all in one kRO but it's from the year of 2009..if I install this and then extract the kro-renewal and kro-rag-lite to the folder..will it damage the content of it..??
