Purchased Artist 8.5, can't use Pro 8.5 Trial

So I just bought Cubase Artist 8.5 which came with a 24 hour trial for Pro 8.5 which I was using for about 6 hours. Cubase Pro 8.5 crashed and then when I re-opened I accidentally clicked on Artist 8.5 instead of Pro. Now I can’t get back to the pro version which I would like to use for my last 18 hours. Any help would be appreciated, and sorry if this is in the wrong section, I’m new here.
