Spitfire on my tail-part2

[DoolittleRaider]

I've enjoyed first few missions of Spit on My Tail Part 1.

I have manually installed SOMT Part 2, following Readme Install instructions carefully... I don't see SOMT Part 2 in the in-game Campaign selection list. I double checked, and confirmed, that I had properly installed it.

Will Part 2 automatically "execute" when the last mission (#40) of Part 1 ends, or should it be showing in the Campaign list right now??
