The file err.log stores important status outputs of the Catan Online World client. Errors occurring during operation will also be specified there. Therefore, this error log ("err" / "log") often greatly helps the programmers to find out about program errors.
Depending on your operating system (Windows, Linux, or Mac OS X) there are different aspects to be noted.
You find a link to the installation folder under Start -> All Programs -> Catan GmbH -> Catan Online World - Follow this link to open the file explorer. You will find the err.log there.
If you have installed the COW in the default folder, you will find the err.log file at
C:\Program Files\Catan GmbH\Catan Online Welt 3\
To access this folder, open the Windows Explorer via the Start Menu (Start / (All) Programms / Accessories) or by simultanously pressing Win-E (the Windows key on the lower left of your keyboard together with the letter E).
If the file extensions are hidden for known file types (standard setting), the file will be just be called "err" (without ".log").
The file will be continued every time you start the COW client. If you completely uninstall and then reinstall the COW client, an empty err.log file will be created in the above mentioned folder.
If you use the regular COW client, the err.log will be continued every time you start this program, just like in Windows Vista.
However, instead of the regular COW client you can also start the program "CatanOnlineWelt-Debug" or "CatanOnlineWelt-Debug.bat" in the above mentioned folder. This way, a new, empty err.log will be generated. (Please note: This procedure will not work when you use Windows Vista.)
Unpacking the installation archive will create a folder named "COW-Client" with an empty err.log. It will be continued every time you start the regular COW starter script COWStarter.sh.
Instead of the regular COW client, you can also start the starter script COWStarter-debug.sh in the above mentioned folder. This way, a new, empty err.log will be generated.
Please go to the Applications folder or wherever you installed the program icon "Catan-Onlinewelt". Click "Catan-Onlinewelt" with your right mouse key (or click it while holding down the Ctrl key) and select "Show package content."
Go to /Contents/Resources/Catan-Onlinewelt
There you find the file err.log
During the respective program run in Windows, Linux, or Mac OS X, the err.log file will be filled with status and error messages. Please send us the resulting file for closer examination.
