I'm getting TGZ files instead of ACE files for Operation Flashpoint

[Schwartsenegger]

He gangsters, can anybody help me.
I've got a cd copy of Op. Flashpoint. I completed the game but I want to try the extra missions and guns which are in the new patch. (ultimate_upgrade 1)
I downloaded the 2 files. The small one is ok , but the big one (5.1 mb) keeps coming in as a .TGZ file instead of a .ACE file.

This way I can never find the "Patch.reg" file.
Is this "Patch.reg" file inside the .ACE patch?

Please tell me what I'm doing wrong!!!!???

Thanx,
Schwartsenegger
