Help with Elements 14!

Ok, I am the least tech savvy person out there so please be patient with my question. Years back I purchased Elements 14 at best buy, have used it ever since then no issues. Last night I had issues restarting my laptop, and I know this is bad but it seriously did not want to turn off so i held the power button down. Turned it back, everything seemed fine then when I tried opening Photoshop Elements 14 it wanted me to sign in despite me always being signed in. It was late and I did not remember my password so I just went to bed and made sure to restart my laptop the proper way. A day later I'm trying to use it and it still was having me sign in despite me always being logged in, didn't remember my password so I reset it. Went through all the verifications with phones and emails etc was able to do it. Signed in and then it's still saying its a trial! I purchased it and i have no idea where my serial number is! Anyone have solutions?
