Hi Fifi!
I'm sorry for the questions but:
-Do you have TWoS 2.2.0 installed?
Then you should have the file "UMark.dds" 5.616 bytes in the data\Misc\ folder.
-Do you have TWoS 2.0.0 installed?
Then in the data\Misc\ folder you have the file "UMark.dds-remove" 0 bytes. This file is enabled by TWoS 2.0.0 and also by TWoS 1.0.6 which deletes the original "UMark.dds" file, so this version removes the "UMark.dds" file and you can not get the U-Mark.
To get the U-Mark with 2.0.0, after installation, you have to delete the file "UMark.dds-remove" in data\Misc\ and in the same folder you have to put the original "UMark.dds" file, if you saved it. If you can not find the original file, I can pass it, or you can use the TheBerbster mod with JSGME.
The version 2.2.0 does not contain the file "UMark.dds-remove" so no problem, but before activating 2.2.0 check that "UMark.dds-remove" is not already present in the data\Misc\ folder of SH5, in case affirmative you have to delete it and, if there is not the file, then insert the original file "UMark.dds" or use the TheBerbster's mod with JSGME and finally activate TWoS 2.2.0.
