Students,
Please ask your professor to file a XUP webcase for you, if he/she agrees that yours is a problem that requires our help.
It is impossible for Xilinx to support all students directly, so our XUP program includes a means of support, through your professor.
As an ex-professor myself, I actually appreciated it when a student came to my office hours. It is a very boring time, when no one shows up, and yet you are well aware that everyone can't possibly be a genius!
So, do your prof a favor: pay them a visit, and maybe he or she will agree that the problem is one that they should send to our support group. The best case is that they solve your problem right there. The worst case is that the professor realizes that you are not stupid, and are willing to ask for help (a real asset when you then go to work somewhere -- employers don't really want to hire people who beat their heads against the walls, and stay "stuck").
