Cannot Activate Smartware Pro

Got the email with the activation code which cost me $39.95. Repeatedly tried to activate the software and continue to get a message saying “There was a problem trying to validate your activation code. Please try again later.” 

Have tried over and over for the past ten days - sames result.

Tried to email support, impossible to navigate the puzzle of the WD Sotre support.  Seems they are only open six hours a day 5 days a week to call.

Any other suggestions?
