Wouldn't you know it, Artur.  I'm up and louder than ever - and this is what I get when I click on your tutorial link:

"This content is currently unavailable. Please contact the content owner for more information."

So, apparently your bandwidth has been exceeded, and the material is unavailable for now.  As you indicated earlier, I will just wait until Geekatplay has your tutorial, so please let us know when it's up.
