i deleted eagle reinstalled it redownloaded the cam addins for eagle put them in the cam file still get an error with the cam file above, the cam file direct from itead does the same thing when i download it and try to use it,the one from seeed its only 2.45kb and when i unzip it says that its corrupted and cant be used.so i guess will just have to hope that when you guys design something that i want to build too ,that you post the gerbers to it
