Well, there's no problem with the theme file itself, the problem occurs with the *.swf file that I assign to that theme. A the end of the theme.xml there's a line that points to the location of that *.swf file (something like desktop style=***.swf...). I change that line with the swf file name and it works, but i Cant enter any menus (the new layout of the menu i recognized, but no way to enter it)
