Game not working right

[Desertmole]

My info:

System: Windows 7 Home Premium all patches current.

Computer: Alienware M15x (2 years old). Intel i7 processor 8 Gb RAM

Game version: 1.8.0.4

I am playing a modified version of the 1941-1946 Campaign. I have added Sea Hurricane aircraft to the database, using the standard Hurricane data, but indicating it is a carrier fighter.

Problem: I have a task force with 3 RN CVs. It just left port on a mission to follow a bombardment task force. The three carriers have 1 Martlet squadron a piece, and one carrier is also carrying a 9 plane Sea Hurricane squadron. I have set the mission for the Martlet squadrons as Escort, 60% CAP at 34,900 ft.

The issue is that since upgrading from Fulmars to Martlets, the fighter squadrons will not fly. I have checked all settings, the carriers have the full number of sorties available and are not overloaded, having 33 aircraft per (max load is 33). The fighter squadrons are a 1-3 fatigue, morale at 99 and experience at 60 or better. Leaders are also 60 plus in Leadership and Initiative ratings.

Am I doing something wrong? I've been playing WITP since it came out. Could the game be corrupted and need reinstalling?

Thanks.
