The license codes are case sensitive - upper and lower case must be entered correctly. There are 4 sets of letters and numbers. One set for each of the 4 text boxes on the enter license panel.
The best method is to copy and the paste each of the individual sets of numbers right from our order fulfillment email into the 4 boxes on the license enter panel. When you copy from the email, double click the number set rather than dragging across all the number as the later technique may leave one off.
You can get to the enter license panel from the "About EazyDraw" menu selection under the EazyDraw main menu.
After copying the 4 set of numbers, hit the tab key one more time to cause a test read of the code- then the "Enter" button should enable and turn blue, this is the first check. If it doesn't enable, check again something went wrong.
After the Enter button enables click it with the mouse and you should be running.
You should test if the code was fully accepted by creating about 40 objects. Draw one Rectangle the do select all "Cmd A" and copy "Cmd C" and paste "Cmd V" - repeat this 8 or 9 times. Or you could quit EazyDraw and re-launch, if you still get the "Enter License" message, a problem remains.
