Probably you have tried to copy the code by entering character by character with the keyboard. Since the code consists of a large number of incoherent characters, copying the code faultlessly by hand is hardly possible.
A much better way is this one:<ul><li>Open the eMail with the license code.
<li>Double click the code. The code is now highlighted completely.
<li>Simultaneously click the keys Ctrl+C. This copies the code into the clipboard.
<li>Enter the license code into the accordant window by simultaneously clicking the Ctrl+V keys. These keys recall the contents of the clipboard.
<li>Click OK.
</ul>
