MT4 difficulties

 
Why do I continually get a "your copy is not activated" followed by an activation key#. I have no idea what do do with it
 
Have you added a commercial EA to a chart (check the top right corner)? If so, then check the EA's docs for the activation process. Could be you need to enter it on a website, then run a supplied dll. Or it could be as simple as right clicking the chart, selecting modify EA and entering the key in the correct extern parameter field. CB
