Issue

When using Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1 with Server Message Block version 2 (SMB2), applications that require real-time file information from files accessed over a network may become corrupted and unstable.

The SMB2 file sharing protocol affects all versions of Working Papers. If there is data corruption you will receive error messages like "Error -310: Not a correct index file" and "Inconsistent Database Indices Detected".
