If you try to ring Support you won't be able to get assistance unless you have your Contact ID number. If you aren't sure what it is you are probably best off contacting Customer Care first and they'll be able to help you figure out what it is. For Customer Care to help you'll need your license certificate which you must have as you would have needed the serial number on the license certifiate to get your license file you installed to the product.
