scrivener trial ending early

Hi there!
I’m currently experiencing an issue with my free trial. I downloaded the software on Nov 1 or 2 for Nanowrimo, and I’ve only used it for about 10 days. I tried opening up the program just now and I’m getting a message telling me my trial period has ended, and that I need to purchase a license. I’ve never used Scrivener before, either on this computer or anywhere else, and I’m not sure how to fix this.

I found that some people were having this issue back in 2016, and it looks like their issues got sorted out. Would appreciate any help! I’m a broke college student who can’t currently afford the full version of the software :cry:
Thanks so much in advance!
