Mine did not ask for the credit card, they added the license to my cam plus account I have for the other 4 WCO. It now says I have one license available. I think I have to wait until the trial is up in 12 more days because the V3 I want to put it on is still on the trial list and not on the list of available device to apply the new license to yet. I tried to delete it from the trial list without any luck?
Note: Since they added the new license to my existing cam plus account which is due to renew in November they gave me a 3 month credit back to my card so I am only pay for 9 months for the V3 license.
