I'm trying to access a file that someone is sharing with me in Dropbox, and I can't get past the screen that forces me to upgrade. I have the basic plan that limits me to 2G. According to Dropbox, I'm using 1.02G (which is interesting because two hours ago when I logged in, I was using .97G and haven't touched anything). Does anyone know why this would be happening? I don't have any linked accounts, and everything that is stored in my Dropbox is visible on my account page so I'm not sure why Dropbox would think I'm using too much base while simultaneously acknowledging that I'm not using all my space. I kind of don't want to upgrade just a few a single file--assuming I will be able to view that file after I upgrade. I guess I have no way of knowing until I upgrade.
