If to speak shortly I has found out the reason of a mistake.
The Construct does not allow to load many pictures - sprite, titlebackground.
Most likely there is what that a limit.... Which then gives out a mistake...... I Declare IT IS BUG!!!!!
It is checked up if will remove one-two - a file that all starts to work! But if again to load files back that again a mistake!!!!! Till now anybody in given situation has not helped me. It is sad.
