I have bought the license through ebay... sealed copy and all. So yeah I payed around 175$. Everything is working as the program should but I have a limit of 500 lines that Mach3 only reads the rest gets cut off... I've looked for the License Files and have both in the Mach3 folder aswell. "License", and "Mach1Lic". How can I resolve this problem hopefully without having to purchase another License.. and FYI. I'm using it off a computer with no Internet access.
