I follow the guide for the second time, but when I reach that point is difficult to continue.
Answering to Mrsmite
Yes but in tools there isn't any option that says "load sql file".
I have made a screenshot to giustify what I am saying.
But, after having done the many points of the guide, I arrive always in the same conditions of the upper screenshot (before refollow the processes I have deleted trinity and build folder and unistalled obviusly all the programs).
In heidisql i haven't put any startup script, and I have selected no databases.
Always sorry for my english and thanks to the help that are you giving to me .
