Upgrade from iBaccs

Same situation than Sergio. I can't see my license number in my actual SDL account, nor in another sdl account with the same email than my ibaccs account (adsum@aliciamartorell.es)

I received (longtime ago) an email with an activation code, but I never received another email about upgrading.  

And now I'm receiving a mail for purchase TBM 6 and it seems that I never purchased it !

Can you help me ? Can I upgrade to TBM 6 only with my activation code, even if my licese dont't appears ? Can I use my actual database without problem ?

Thank you
