Hi,
I have the same problem everytime I update.
The problem I have found is that some of the config files in res_mods\configs\xvm\Aslain are created only with administrator privileges.
Also some files like:
res_mods\0.9.10\gui\avatar_input_handler.xml
res_mods\0.9.10\gui\NoScroll.xml
res_mods\0.9.10\gui\ServerCross2.xml
res_mods\configs\DamageLog\Log.cfg
When I add privileges to the "autenticated users" group on those files, the game works again.
Hope this will help to solve the problem
