Hi Adrianr,
Thanks for your response. I saw that the wiki had a "contact info" subtitle at the end of it, which I missed completely! I already sent an e-mail to Felix and I'm awaiting his response.
Nevertheless, I already followed all the instructions regarding the uploading of the Fritzing files to start the production of several PCBs, so I'm just curious of the reason the others don't work. I just want to know if I have missed other info regarding the design rules, or if I need to put this other PCBs in production elsewhere as I have personal deadlines approaching...
Best,
Jorge
