If your license activated successfully, as indicated by the message you received, but your software remains feature limited, the first thing to check is that you're licensing the right product.
Check the end section of your license code. It should end with something like "-FSSTU21.2". This indicates a FlexSim (FS) Student (STU) license for version 21.2 (works for any 21.2.x bugfix).
My best guess is that your license is probably 21.1 or older, and so doesn't license our latest 21.2 software.
I don't actually see any licenses under your FlexSim account. To continue this discussion specifically for your license, start a NEW question and be sure to mark it as PRIVATE. Then we can share license information and discuss your license specifics.
