[MonoDevelop] Activation code

[GREGORY AGATHANGELIDIS]

Dear  all,
I have some question about monodevelop.
The my current version has the follow data:

Release ID: 20402005
Git revision: b7eeb779e1134c204f22d9fd5b6ebec4d758f60d
Build date: 2011-04-22 22:48:43+0000

I would like  to install the update:
monotouch-4-0.3.dmg
But I receive  prompt window which requires  my activation code.
However I do't know how and where  to retrieve my activation code
Please for any help
Many thanks
