Ok, I installed now every package found when I enter l3 and fontspec but I still get the same errors. I reconfigured lyx after installing the packages of course. Is there any other specific package I need that is part of latex3 and doesn't start with 'l3'? When I filter the packages for latex3 the package manager finds nothing. Thanks for the help so far.
