whiteside,
That's strange, because the S-3B by Dino is supported by default (as long as its atc_model parameter equals to 'S3').
As for your problem, I'd like to clarify some of the details...
Does 'No recog of dinos s3 in-sim' mean that you're getting 'unsupported aircraft' messages when flying the S-3B?
Saying 'no aircraft listed under the list of aircraft like before' do you mean that the 'Custom aircraft definitions' list is empty? True, this list is empty because the default .ini file, bundled with the program, has no custom AC definitions anymore.
And finally, does 'Tankers are all recognized' mean that the 'Tanker aircraft' drop-down list is filled with airplanes, currently present in your FS, and your tanker is highlighted?
