Can't I use CubaseLE?

Hello, I’m a beginner highschool student . I have a question I wanted to ask about downloading CubaseLE.
I previously purchased a ZOOM G6 processor and used CubaseLE with the license that came with it.
But one day my PC had a problem and I had to reset it to its initial state.
And today I tried to reinstall CubaseLE, but it said “This download access code has already been used by another user”. Am I unable to use this license forever?
