Bought it Years ago, wanted to use it again, Key is not working anymore [Solved]

[SirIkaros]

Years ago my friend bought me Cubik Studio to work with.
Yesterday after years of not using it, I tried to re-log into my account here on this page I seemed to have, failing.
Entering my license didn't activate the account. I used my address I always used and also his since we didn't know which account we used.

So I only have a key which doesn't seem to work, no matter what I do. Maybe someone can help me ?
