I thought this was just a Windows 8 issue, but it appears to be a Safebox issue: If you have 2 computers (Computer A and Computer B ) with Total Security 2014 or 2013 and Safebox activated, the folders can't be accessed. If Computer A has a folder synced to Safebox and Computer B also syncs to that folder, (like the SafeBox Folder), you will get an Access Denied error.
