The cookie our system creates is setup so our system knows which affiliate is connected to the order, it will not necessarily look the way you are expecting. I would suggest that you recopy and paste your affiliate code from E-junkie.
If you would like to run a test to verify that the cookie works, you will need to contact the merchant directly. E-junkie is just an automated software service that thousands of merchants (sellers) use to manage their own Affiliate program independently, so we have no way of knowing what instructions they may want you to follow or how they choose to administer their program using our software.
