Ok, posting in the proper thread... (sorry)
I had to edit my air, ships, stationary and cheifs ini files to get mine running, the following classes were showing as missing:
Several Ju-88s
P.7 (Poland)
RWD 12
Do-24s (all)
Yamato_1942
Musashi
Plus the loadouts on the HS-126 were showing errors in the log. If needed I can re-install the update to provide the log but I think you guys probably have a good idea of what it would say from this information.
There was also a duplicate Engine mod file in the BAT mods folder, well not exact duplicate but it looked like an old version had been left in with the newer one having "BAT" added to the title. Just let me know if you need any more info. I might go for a complete re-install since I must have missed an instruction on one of the updates somewhere along the line so I'm pretty sure it's my own fault somehow but, just in case it is helpful information, this is what happened with BATEP09 for me.
P.S. I have tried re-installing BATEP09, didn't work for me.
