I don't think it's a great idea to discuss a pirated copy of eagle 4.13 on these forums. Eagle does seem to have good copy protection, and in every case I have seen, a pirated copy of eagle will randomly corrupt any files you edit with it after a few days or weeks, and even before that happens, any files you edit with it will be unusable by other people with legitimate versions; if they try to open them it will display a message saying that the file was edited with an illegal copy of Eagle. So, using an illegal copy of eagle is not only immoral and illegal, it's also really shooting yourself in the foot, which you'll surely realize the first time you spend countless hours designing a complicated schematic and PCB layout, and then find one day that it has been corrupted and you have to start all over.
