CDC and LCD

[Rorix]

Hi there, I'm having some problems with a project I'm working on.
I don't have the code at the moment since I'm not at home, but I'll try to explain it:

1.- First all the CDC needed fuses, clocks and stuff
2.- The LCD include libraries
3.- Initialize LCD and CDC
4.- A led should turn on here just to check the communication is done

The issue here is that nothing happens. My PC won't recognize the CDC or show me the virtual port.
So I'm wondering what to do, cause if I remove the lcd part works like a charm.

I'll post code later, for now give me some ideas.
thanks
