Using Trial Version -- Nothing Happens with Plugin

I just downloaded the trial version, loaded it into Lightroom Classic 9.2 in Windows 10 and converted one image taken with my Nikon D750. It worked pretty well. I then took another few photos of additional negatives and tried to convert 10. Nothing happened, but the trial version now tells me that I have no more trials left. So I am now stuck not knowing if it will work and can no longer try anything in NLP. I looked over the Forum and did not find this exact situation. Some of the suggested solutions don’t work for me because I cannot do any more conversions.

What now?
