Mine says v 0.25 in readme, xpak.exe is dated 8/10/2004.
But I've not heard of any problems with any version.
Do you have both the .bat and the xpak.exe in the same folder as the patch_0.pak ? Not sure how you would have got directory structure if not but its only thing I can think of!
Theres a tutorial on using xpak here:

in case that says anything I've forgotten.
