Ok. I was irritated because your Windows don't even know "´". First, please download "Notepad++" again.
At first go again to the main directory "OMSI2/Sceneryobjects/Nemolus Objekte". Look for "VZ_Mast_Vorfahrtstraße.sco" copy this file and rename it into "VZ_Mast_Vorfahrtstrasse.sco". Then go to "OMSI2/maps/Dobel" and click at "Type" that all the same filetypes are in a row. Mark ALL "MAP-Datei", rightclick their and then "Edit with Notepad++". All "MAP-Datei" now should be open with Notepad++.
In Notepad++ you go to "Search" and next "Replace". In the line "Find what" you enter "VZ_Mast_Vorfahrtstraße.sco" and in the line "Replace with" "VZ_Mast_Vorfahrtstrasse.sco". Now click the button at the right side "Replace All in All Opened Documents". In the bottom of that window you should see that xx Files were replaced. Now you can close this window. At last step you go in the top of Notepad++ and open "File" and click "Save All". The problem with "VZ_Mast_Vorfahrtstraße.sco" should be solved.
When you look at your logfile from Wednesday the next problem is in line 56 with "VKL?s Splines". The original folder called "VKL´s Splines". Now copy this folder and rename it, as example into "VKLs Splines". Open all "MAP-Datei" again with Notepad++. As next you have to make the same things as above. But in the line "Find what" you enter "VKL´s" and in the line "Replace with" "VKLs".
In your logfile you have to search for all errors they contain a "?". As next as example in line 69 "BMOTree?s". The name of the original folder is "BMOTree´s".
When you have change all of this folders or files you can start your OMSI an the map Dobel. But the next errors will come definitely. There much more files in the map with "ä, ö, ß,ü".
I know, that's much work to do, but when the map is running you wouldn't regret it.
I wish you good luck, if you go the way I told you.
