My access code suddenly became invalid

Back in June I received an Access code for 1 year from my summer camp as a bonus. However, when I tried to log in today (btw, Construct constantly asks me log in and re-enter my access code each time I open it) My code suddenly became invalid. I tried different browsers and devices, but nothing works.

Access codes are distributed by the subscription owner - if it's now invalid or withdrawn you need to contact whoever gave it to you to ask why.
