For the record, I wrote the installation instructions. Trust me, please set ETO to Era 1 and the Spawn Selector to #1, Stock Spawn Mode before installing ANY ETO Update. I would NOT lead you astray.
For the sake of clarity, yes, ETO has an AI Stirling, but no Hampden as yet. I believe someone was working on that item, but i can't remember who.
You would need AIREd program to change the plane's *.air file to make it player flyable.
You can quickly and easily tell if your global layers are corrupted by going into Era 1 and looking for the Spanish airfields. If they are not available, the global layers are corrupted.
