When I try to play the Opposing fronts campaigns, it says that I do not have the required data installed. I have retail versions of the original CoH and Opposing fronts.
There is a padlock icon over the OF campaigns, clicking on it prompts me to enter a CD-key, but when I enter the CD-key, it says that the CD-key is already registered to my account.
The OF installer says that OF is already installed.
Congratulations relic on one of the most torturous and confusing installation procedures in PC gaming history.
