AtomicA_network, you replied to a thread from over a year ago. Indeed the prior post had been done on the last day of that early 2015 five-week Pacific event.
That was the first public shot at the WaW Pacific set of maps for FH2. Since that time, it has been integrated into a set of custom maps, known as the Community MapPack V2 (CMP V2). It includes updated Pacific maps, but also custom maps from around the FH2 community: Forgotten Honor, 762 Ranking, and World at War.
I understand that some maps in the CMP V2 had single player capability, but generally they are intended for multiplayer. Yup, as jan_kurator said, there was an FH2 update. It was earlier this year. Thus, the crashes.
Right now, there is significant work on an update to the CMP V2.
