I think I found the answer to your problem. Try the following:
In the directory SilentHunterIII\data\Movies\Intro you will find 2 files. Go there and delete them and give it a try once again.
If this doesn't work, then my advice is to uninstall everything, including remaining filies in the directory (delete), as well as the files that SH3 creates in My Documents (in C: drive).
I would even advice you to run a registry cleaner just to make sure everything related to SH3 has been deleted/erased.
Once you do this, reinstall following this order: install SH3, patch 1.4B and then before installing other mods, delete the files Danlisa and I told you to.
I hope it finally works and in your next post you give us good news.
Good luck
