I hade the same issue and manage to solve it.
I think the issue had to do with the Generic Patcher, I didn't quite understand how to install it the first time around. It was basically to click File - Open then press Yes like 200 times, then click File - Restore snapshot and select the snapshot.
Better explained below, from

- Start TDW GenericPatcher. (TDW_GenericPatcher_v_1_0_164_0)
- Choose English
- Click in the Menu: File > Open
- The TDW GenericPatcher will now ask for some file locations. All the files are located in the SH5 installation path, parallel to the SH5.exe
- All files will get edited so just click [YES].
- Once all the files are choosen and edited you will see a list.
- Choose: File > Restore snapshot > Dragons_GenericPatcher_Snapshot.gps
