If "Access violation at 0x004489C8 (tried to write to 0x00090FFC)" is reported when you start the "Dire Grove, Sacred Grove" game this problem can be resolved using a downloadable update to the installer.
The process is as follows:
- Restart Windows.
- Place the ESS1043 DVD in the PC’s drive - cancel any “Auto play” dialogs or prompts that may appear.
- Download the update via http://supportfiles.focusmm.co.uk/updates/ESS1043_Patch(20150424).exe (choose the "Save" option if offered by your web browser, so that you can rerun it later if necessary without having to download again).
- Run the downloaded update to start the installation and follow the instructions displayed on screen.
You will need the downloaded update each time you install the game from the ESS1043 DVD.
