I have lost access to a shared file on Dropbox. Every time I try to access the file via the email link I've been using, it just says "For some reason that did not work" (translated from German) along with an image of a french bulldog and an empty bowl. I've tried to use different browsers (Google Chrome and Microsoft Edge), but neither of them seem to work. Also, I've received a notification telling me that my storage space has been used up, although I haven't stored any files in my personal DropBox and I've only been using it to access that particular shared file. I'm pretty sure that the owner of the file has not removed me.
My question is: How can I regain access to the folder?
Thank you in advance, I appreciate any help.
