Hi Fen'harel,
When our
ex-publisher put out the boxed version of the game there was a printing error that put the key into the wrong format, which as you can imagine, has caused a number of difficulties.
If you follow the steps in
this post, you should be able to get your key into the correct format.
If you still have difficulties, send an email to
support@reverieworld.com with details of the problem (including your key) and we will sort things out for you.
