Hi Vipaddles,
Welcome to the forum.
You should have unzipped the attachment that came with your license email then copied the .dat file to your Mach3 folder then restarted your PC (just to make certain that files etc. have been updated).
It sounds like that is exactly what you have done so I have no idea just why the license is not working correctly for you.
This section of the forum is mainly for introductions and does not get read by many of the members so it is always best to post any questions, as a new topic, in the relevant section.
The LazyCam section is here
http://www.machsupport.com/forum/index.php/board,14.0.html and I am sure that if you post your question there Rich will know the answer to the problem.
