We are using the free version of Box which includes 100BG of storage.  We reached the limit a while ago and have been getting rid of old files over the last 2 months or so.  I'm still getting a message that we are out of storage but the admin console window show us only using about 35GB of storage.  I just got the message again when trying to upload a file.  We are just a small non-profit using the free version and can't afford to pay at this point.  Please help!  Thank you!
