Yes, he meant GermanyCE_Types.ini.
I would recommend renaming the old one, then installing the new one, that way you can revert later, if desired.
EricJ is correct, it can be a real meat grinder up there in this one, especially if you have the Soviet weapons pack installed.
If you plan to move mud in a dedicated strike aircraft, you will be pushing up daisys. A lot. Some of the added air defenses
will allow you to dart back across the lines for a little friendly SAM assistance.
This is the toughest campaign I've flown in WoX, and i've flown quite a few.
Even dedicated air superiority aircraft are in for quite a tussle...
