Why should i post a log?
A log helps users to solve your crash.

How to open a .log
With the normal editor.

Which file should i choose?
The one after the crash, so the latest one.

What exactly should i post?
The last 10 or 20 lines are enough.
It would be best to upload the log somewhere and post a downloadlink.



1st step: Making hidden folders and documents visible
If you have already done that you can skip that step

open the control panel > folder options
For a better overview change your display settings to big or small symbols



Select the 2nd category on the top
scroll down and make hidden folders and documents visible



2nd step: Opening the right folder and log
For most Windows 7 and Vista user the path should be like that
C:\Users\YourUsername\AppData\Local\Focus Home Interactive\Cities XL 2012\log
XP:
Documents and Settings\AppData\local\FocusHomeInteractive\Cities XL 2011\log
Open the latest .log with editor (important: open the latest file just if you had a crash last time, if you had a regular run it won't be helpfull
rightclick - open with - editor



editor not mentioned?
In open with select the browse button and go to
C:\WINDOWS\System32
and open the notepad.exe



In the log scroll down to the end, and copy the latest 10 or 20 lines in your post/topic

1st step: Make sure your appdata folder is visable (see 1st step how to post a log)

2nd step: Backup your files
Make a copy of your Cities XL 2012/11/09 folder to backup your files
C:\Users\Username\AppData\Local\Focus Home Interactive\Cities XL 2012

Also if you want to continue some cities you should save all your mods.

3rd step: Deleting the savegames/appdata folder
delete this folder:
C:\Users\Username\AppData\Local\Focus Home Interactive\Cities XL 2012\live\offline
(This folder contains all the savegames, settings,...)

If the log links to a special city (optional step)
C:\Users\Username\AppData\Local\Focus Home Interactive\Cities XL 2012\live\offline\solo\solosaveregionmap*
in the solo folder you can find several "solosaveregionmap*" folders which contain the city savegames, in every folder there is a file called: city.cxl
open it with the notepad and search for the line: <itm key = 'CityName' value = 'Cityname' />
(theoretically you could cheat with this file)
that way you can find out which city is in the folder and if your log is linking to a special city, delete the folder (remember, just at a startup crash)

and of course... reinstall your cxl
