Hey ,
Sorry for writing post by post .

I've done some tests and I may cross out some of my speculations ...
I burned few CDs - 1st was with changed navboot and version in 2 .tbl files , 2nd one was with only changed .tbl files , and 3rd was clear but burned by making an image , cause I wanted to check if it's not a burning problem .

What turns out ... 1st and 2nd CD stops in exactly the same moment - it's in "software wird geladen" screen , but the progress bar doesn't appear and it gets stuck . But 3rd CD installs and works pretty well without any troubles .

Conclusion : it's probably fault of changing version in .tbl's . Cause even if it was fault of navboot , the 2nd CD should have installed , am I wrong ?

Now I'm asking you for the solution , 'cause I did everything following the ccfj1's guide replacing 30 into 31 in the hex code with XVI32 . What I might have done wrong ?

Hoping for help ,
