I followed everything and believe me, I searched. I keep getting errors regarding compilation, I've setup two different Flex, 4.6 and 4.16 and no results, I've got 105 errors most of all is these "Error

144, 36) [WebMain]: Error code: 1084: Syntax error: expecting identifier before greaterthan." in ConditionEffects.as.
I tried decompiling with Trillix and compiling with IntellijIDEA the prod clean client and looks like my IntellijIDEA or my Flex is broken(two versions)
Error

36, 42) [WebMain]: Error code: 1046: Type was not found or was not a compile-time constant: kabam****tmg.news.model.NewsCellVO.
Warning

139, 17) [WebMain]: Error code: 1100: Assignment within conditional. Did you mean == instead of =?
UPDATE: Found myself compiling crazy source from SometimesRain, no problems at all, so... does it mean my decompiler made mistakes? so which decompiler should I use?
UPDATE2: Started all over again, and again, and again, finally I've got a lot of PETS errors and an unfinished Player.as which cointains errors
UPDATE3: Does anyone knows how do I get a sucessfull decompilation and compilation of the current prod version?
And, if I get a sucessful compilation, but instead of Play I get a whole black screen, where did I made a mistake?
