Had a registration problem

Hello
I seem to have a big problem with the registration process because right after installation it asked me to activate the software so I used the code that came within the box.
I received an email.
However, now, it keeps asking for it every time I launch Notion 3 and says the code has already been used which means I can only use Notion 3 in demo mode for the next...thirteen days, which sucks because I love that software so far.
I think it has either to do with the update ( downloaded the update and installed it and it started asking me for that serial key once again right after that ) or with the fact that I had tried the demo before installing the full software ( even though I made sure it was entirely uninstalled properly ).
I tried to deactivate that license through License Manager but it says that "This Program is not licensed on that computer"...
I made sure I uninstalled it before installing Notion 3 though...
I've already sent a ticket to support but since it's Christmas and everything, I don't expect an answer soon so I figured I might post here just in case someone knows what to do...
Cheers !
