Renewal of account

I don't think you can syncronise two accounts.  We have been asked this type of question on a few occasions recently, and there doesn't seem to be an easy answer with regards moving from a trial version to the paid for product. 

If you login to your SAFE Portal, and go to Orders and Payments, do you have a button to Enter a Code?  If so, you may be able to enter your new license code there.  If not, then I would suggest you create a Support Ticket, and hopefully they will be able to help.
