Cannot reupload the Enfold template

I previously had a designer upload the enfold template for my website, but when they left they did not leave me a key so I purchased the template myself. I’ve been trying upload the newer version through boy WP and through my FTP and Cpanel, all of which have not worked. WP says that it already exists and there are no updates available. Cpanel says error both when I tried uploading the whole file folder and when i tried to do it individually. I don’t want to lose what i have already made for this website, but I want it updated
