A friend sent me an invitation to join a shared folder. When I tried to accept it, Dropbox asked me what I wanted to do with all my files! It wants me to create a whole new dropbox account in order to keep my files separate from the folder I've been invited to join. This has never happened before and I can't find a way around it. I just want to join the shared folder- I absolutely do not want to create a new dropbox account in order to do so. I already have a dropbox account!
