Problem 'Cannot import test.reg'

Hello.
I am trying to run a log on script that will set the outlook stationery theme to blank.
I exported the portion of the registry as I would like to have it to a .reg file, which
is stored on a server path of \\server1\public.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\MailSettings]
"MarkCommentsWith"=hex:4e,00,65,00,69,00,62,00,61,00,72,00,67,00,65,00,72,00,\2c,00,20,00,43,00,65,00,6c,00,65,00,73,00,74,00,65,00,00,00
"Template"=hex(2):00,00
"NewTheme"=""

After mapping drives in my log in script, I have inserted the following line
Regedit.exe "\\server1\public/StationeryLD.reg"

It prompts me to accept, then dislayes this message
Cannot import StationeryLD.reg: Error opening the file.

Any help would be greatly appreciated.
Thanks
