NWDS Sneak Preview: Unexpected end of Archive Error

Hi,

I downloaded the NW04 Sneak Preview javafull version. All 5 RAR files were downloaded successfully. But when I try to Unrar it using WinRar, I get the error: 'Unexpected end of archive' for all the files. I have tried to download the complete set 3 times, but the error persists.

Could someone please help me out.

Thanks,

Shobhit
