I am using Windows 7 x64 with 2GB DropBox and using MIcrosoft Office 2010. I have bought the 25 computer subscription and have installed notifybox on 2 computers so far. I have excel sheets that are in shared folders, each folder shared with a different computer, my Dropbox has ALL the folders.
I have tried to open all the excel sheets but have not receipt the "check-out" prompt. I REALLY need this to work and I seem to have tried everything.
