Rhino 6 Evaluation - Can't save

I just downloaded the Rhino 6 Evaluation Trial, which said you could save projects during the trial period, and it says it is already expired. I entered the key twice and it still says expired.

how long have you been using it? the trial is for 90 days only

I just downloaded it today.

Has Rhino ever been on your computer in the past?

@baierjaclyn Please contact sales@mcneel.com directly, they can look up your license history and probably figure out what went wrong and fix it.
