Activation code submission issue

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

@dungvo
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.
