Activation code submission issue

Hi Community
I have put my activation code but cannot submit it. Could you help me this issue? Thank you

Yes, happy to help. There is no feedback when you click Submit other than your Expiration date changing below.
So did your expiration date below change to a date a year in the future?
If yes- that means that your code went through and you can enter the lab!
If no- did you add an extra space, miss the dashes or already use that code on another machine?

Let us know if you have further questions.
