CS6 Programs Disappeared/Not Opening

Hello there,

so perhaps sometime in October I went to open a Photoshop CS6 file and it wasn't working. I thought it was maybe just a one off chance so I restarted my laptop and the issue persisted. I decided to try to just open Photoshop CS6 and then open the file from once inside the program, however it wouldn't even allow me to click it to open it. I then noticed all my other CS6 programs such as Premiere Pro and Illustrator also were giving me the same issues. I'm not quite sure why it is happening because I'm fairly certain I fully bought them two years ago as opposed to paying a monthly subscription (I believe those were my options) and now I can't even open them at all. I decided to take some time away from it and not overreact and after some time had passed, I've now confronted it again and in my Creative Cloud menu, the CS6 programs aren't even listed as available anymore. I'm just wondering if anyone else has had this issue in the past? Or if I maybe was mislead to believe I was buying the CS6 programs fully licensed when I really wasn't and they expired.

Thanks in advance
