Another 1.4 patch problem

[Lugworm]

I came across Silent Hunter III by chance surfing the net about 6 months ago and was captivated by the vids i found on U tube and the like, i quickly found subsim.com and become a regular stowaway to the forum and have been blown away by the enthusiasm folks have and the work the modders do to add to and fettle the subsim. I have always had an interest in shipping since the 60s so the sim is right up my street, i had to have it. I have just got myself a gaming computer together and have just loaded the Europe version of the sim on DVD and tried to update to the Europe 1.4 patch downloaded from the Ubi site. The problem is i get the error message when trying to update as follows c:\program files\ubisoft\silenthunterIII\mission engine.dll:unkown version. any ideas folks, the sim plays fine as it is and is keeping me happy as its all totally new to me, but as i learn the ropes i want to patch and add on the fantastic looking GWX 2.0. I have uninstalled and reinstalled even tried the other USA version of the patch all to no avail, i am a bit of a newbie to the inner workings of computers so can anyone give me any pointers to the problem i am getting, Cheers
