Always run the game in Administrator Mode. This is especially important for Windows 8 / 8.1 users.
Locate the "Allods Online EN" folder.
- I used the old gPotato NA client, so my folder was located at: C:\gPotato.com\Allods Online\Allods Online EN
- If you still can't find it, search your PC for an "Allods Online EN" folder.
Open the "bin" folder.
Right click AOgame.exe > Properties > Compatibility tab > Check "Run this program as an Administrator".
Press Ok.
In the same folder, right click Launcher.exe > Send to > Desktop (Create Shortcut)
And launch from the new desktop shortcut every time you want to start Allods. This should fix most problems. Reply if you still have issues.
