I have been a user on a church's account for years. They pay for dropbox and upload videos into their folder and I go on to their account for purposes of downloading the video for use elsewhere. This has been the case for at least 4 years. Now I can't access their folder anymore because dropbox says that my account is out of space, even though there are 0 files in my account. This doesn't make sense. The church is already paying for the space. I am not doing anything except downloading files from a folder that is being paid for by someone else. What reason would I need to upgrade my account?
