well, dude I threw your map up in my mod that I'm making, "Peace's Rest". I didn't like it so much.
according to the debug assertion : it can't find the Sky_Bocage_m1.sm... basically you don't have that in your standardmesh folder... which is strange because you should unless you deleted it. try running the map in your vanilla bf1942 and see if it runs. I recommend you download the debugger in the download section. it's great when making a new map where anything could be wrong.
just put the sea_battle.rfa in your bf1942/levels/ directory and run it from bf1942, or the debug version which I suggest. and please take a screen shot when the debug assertion pops up please it will look like this:debug ass.jpg
