My account keeps saying it's full - but it isn't

Dear Megan: thanks! I already solved the issue. What I may suggest is a step-by-step tutorial of what somebody must do to empty one's storage room and for that to be acknowledged by Dropbox and reflected on one's account. I don't know whether it's just an impression or a fact, but every single detail of the solution procedure seems to indicate that Dropbox does NOT want us to empty the box so that the only option remaining is for us to pay for additional space. In the era of transparency that's not good advertising for Dropbox. If they offer free space they should respect that decision, at least for those who registered ages ago. Of course they are free to do what they want but if it's not transparent... Thanks again!
