Neverwinter Nights No-CD 1.27
 

I'm trying to download the Neverwinter Nights 1.27 No CD patch file "grunwn127cd.rar" and it seems the rar file is corrupt. I've tried multiple mirrors but I keep getting the message
"! C:\Documents and Settings\Legion\Desktop\grunwn127cd.rar: Unknown method in nwmain.exe
! C:\Documents and Settings\Legion\Desktop\grunwn127cd.rar: Unknown method in grunwn127cd.nfo
! C:\Documents and Settings\Legion\Desktop\grunwn127cd.rar: No files to extract"

Can anyone tell me if it could be just my unrar program, or has anyone else been having this problem.

Thanks for your help,

Legion
