I never had any problem getting TIR to work in WOP. My mini-review: amazing graphics, good sounds, typically twitchy & bizarre IL2-style flight dynamics, laughable radio chatter that belies their non-native English-speaking roots. Overall a strange mix of highly immersive and arcadish. Of course I'm a crap shot, so a little arcade-style play was actually sort of satisfying. I played it for a couple of weeks, but haven't launched it again since.
On a side note, is anybody here familiar with "It's Always Sunny in Philadelphia"? One of the voice actors - the guy who's always yelling "I can't see him!" - sounds exactly like Charlie. Cracked me up every time I heard it.
