It seems that I face a problem regarding the installation... I followed all the steps described below but it does simply not work

1. Unzip the basic mod v1.05.
2. Create a new folder e.g. "PHCAS Gold Mod V.1.18" or something similar.
3. Put all the content of the folder "Panzer Corps" from your unzipped basic mod v.1.05 into the newly created. Now you have the following structure: "PHCAS Gold Mod V.1.18\Audio, Data, DLC, Expansion, Expansion2, Graphics,UI" "
4. Unzip the cumulative update v.1.06 to v.1.16 and copy that folders in your "PHCAS Gold Mod V.1.18" (some files will be overwritten). Now you have v.1.16.
5. Unzip the v.1.17 update and do the same.
6. Unzip the v.1.18 update and do the same. Now you are up to date.
7. Copy the "PHCAS Gold Mod V.1.18" folder in the GME MODS folder in your Panzer Corps main directory.
Can you please help?
