Strange error while installing Kursk DLC

[vonotto]

I tried the link from the new email you sent me and still get the same error.

Did you do the Update of the core game first as well?

[vonotto]

Core game says it is up to date when I click on update. I have no idea what else to do.

Looks like you have done the correct procedure.You need help from the Matrix Staff here. We could see if they jump in on this thread or you can contact them through the Helpdesk on the Members page

FIXED...

For anyone else having this issue:
1 - Completely uninstall the game.
2 - Reinstall main game.
3 - Install Patch.
4 - Install Kursk.

Also DO NOT AUTO RUN THE DOWNLOADS, save to desktop then open files and install them.
I want to thank the Matrix team for the fast response to my help desk ticket.
