Sakray Extraction

[Xenn]

So a friend reccomended this server (And game) to me last night, thought I'd try it out.  Downloaded the KRO and updated (I think), downloaded the Sakray Part one and two.  I don't know how to extract the parts into one file, but this is what I got when I looked it up on YouTube, and tried it myself to Extract Files... onto my desktop

Code:

!   D:\Users\PaperClock\Desktop\s0325.part1of2.rar: CRC failed in SAK_SETUP0325.exe. The file is corrupt
!   D:\Users\PaperClock\Desktop\s0325.part1of2.rar: Unexpected end of archive
!   D:\Users\PaperClock\Desktop\s0325.part1of2.rar: Packed data CRC failed in SAK_SETUP0325.exe. The volume is corrupt

Anyone want to tell me what I did wrong and how to fix it?

Last I checked, You are supposed to take both parts of sakray and put them in one folder.  Then extract part one into said folder and it should work.  (Extracting the first leads to it auto-extracting the whole thing)
