Activation does not work and this with two keys

What is going on with the activation here??? I bought a year ago the basic-> NO problem here on W7 64x!

But now I have bought me the Pro now and get error that the key is not valid. Ok, have emailed for help but no real fix, so they refunded me and then I bought back the basic and again key does not work!!

Look people if you want to earn money than make sure it is working bc I am a power user with over 130 programs online and no problems with it all, but this I cannot get activated!! This needs to change bc there are more with this problem when searching and never had this before with any activation.
