THX for fast reply, Malone!
So, i have 4.10.1 with UP3RC4. The so called one-step easy install...
I have another aircraft mods, but no Do-335 mods at all. Not even new Do-335 skins.
Added the latest buttons to 4.10.1.(2014 Juny load...) Also have Benitomuso1s AutoDiffFM. So, i succesfully installed planes whitch needed DiffFM, without DBW. For example, Go-229 A3 and Go-229 A3 NJG.
Plus: Ta-183 and Me-262 with homing missiles, Go-229A2, He-177, Ki-45, 51, 67,109,177. Late Corsairs, Whirlwind, Meteors, La-9/11, Ju-188A, Ju-88G1, Hs-123A-B, Cant 506, Me-509, Bv-237, Kingfisher, B7A, Autogiro, PWS-26, B-26, P-61. Ar-234C, FA helicopter. Akizuki DD pack, Corvette+escort pack, Jagdtiger+quad20mm pack. All of them tested. QMB, FMB, friendly and enemy units...worked well together with other stock UP3 planes and vehicles...
I have a saved mission file in QMB. Enemy planes are Fw-190D-15, Me-410D and Bf-190K-6. My flight are Whirlwinds, plus other russian/american planes. Everything is OK. After, i have changed the Me-410 planes to Do-335 pfeils, and things happened...
So, i have tryed to do what you are advised! If will not work, log file posted!
Very THX! Mopat.
