I cancelled my team plan and now I can't access any of my files

I had a dropbox business account for 3 users for several years. I closed the business and cancelled the dropbox subscription in march 2024. I thought i would be able to have access to the files after I stopped paying for the subscription because my Dropbox folder was on my C: drive of my computers, but i would lose the sharing capability. Well turns out most of my files were or are now set to “cloud only” or something like that and i cant access them on my c: drive. My old business account reverted to a basic, non paid account but i dont see any of my old files on that account. I still have all the old folders of my old dropbox account on my c drive but the files are in accessible. 

is there any way to get these files back?
