S H A M E ON M E !!!!!!!!
Thank you guys for your help!
I was really confused, it all was caused by this fuss connected with a bug.
I thought that because of this bug it is impossible to go through and pass the game.
Every episode of Guybrush and his adventures I've passed by myself without any solution.
I am really embarrassed that I asked for a help.
If not you I would still sit before my PC and think why It is me! Why I've bugged game and can't pass it.
Thank you one more time and sorry for panic ^.^
