Offline Installer Troubles

[Rasteel Olin]

Well, I have the **OFFLINE** (Edited, sorry mis typed it) installer.
I run it, it seems to download everything fine until It tells me that Java will download the game now.
I press 'okay',
and it starts downloading, and then java opens this error:
"Unable to import Illarion Client."

Here are the details:

Under General:
An error occurred while importing the application.

What to do, and is there a way to fix the offline client?

[Rasteel Olin]

From reading the error file, my guess is that I need this file:
C:\DOCUME~1\KARLSA~1\LOCALS~1\Temp\nsw10.tmp\illarion_client.jnlp

Where to get it?
Is that the problem?
