This license key is already registered in a different account

Hello support,
I was just checking my information and tried to sign into the app. Once signed in it asked me to provide my activation key.
That took a while to find, and logging into the online portal, the key was not present there either. Trying to register it I get the following error "This license key is already registered in a different account.".

Please help.

 

Hey, can you please let me know what your support email is? I do not use facebook or twitter, and I don't seem to get any response here...
