Windows Vista: Installing SH3 and Patching 1.4b

[croozer]

I have no idea if this is the correct place to post this but I'm having problems with the 1.4B patch

I'm trying to upgrade to GWX 3.0 (I had 2.1)
I have a 2005 V1.0 US dvd edition of SH3 - Windows XP

I deleted all of the SH3 files and reinstalled
When I try the 1.4b patch (the US dvd version) it won't run - I get this error

c:\program files\Ubisoft\Silenthunter111\data\menu\de_help.tx t:unknown version

Ubisoft sdays the previous patches have to be installed in order but the GWX instructions say not.
ANy ideas? (I'm not a computer guy - I just like the game)

Thanks
