cant resume unreal 4.12.3, tried restart system, tried reinstalling launcher and reinstalling engine, but i got struck somewhere. it is very difficult to continue with the unreal, please distribute a single copy of installation file so that user has to pay attention on his project not the bugs generated by the application. it is very disappointment. most of my friends suggested me to shift to another engine like unity and cryengine and now its time to change my mind. i am got fed-up of logging and reporting bugs to unreal.
