10.1 I can't get a connection.
10.2 Windows Error Messages
10.3 Cascade DataHub Error Messages
10.4 Messages from Excel

10.1.	I can't get a connection.
	Check the following: Is your connection to the Internet and/or network up and functioning normally? Does your firewall allow a local program (like Cascade DataHub) to act as a server? Does the Cascade DataHub run OK? Is the DataHub installed and configured correctly? For drag and drop operations, is the Drag & Drop Style at the bottom of the Data Browser set to MS-Office (Excel/Word)?
10.2.	Windows Error Messages
	For a list of Windows error messages, including those for TCP and DDE, please refer to Appendix G, Error Messages.
10.3.	Cascade DataHub Error Messages
	Here is a brief explanation of some of the more common error messages you might encounter when using the Cascade DataHub: License failure: License in use by master There are two possible reasons for this message: One Cascade DataHub is mirroring to another DataHub on another computer and that DataHub is mirroring back to the first. The Cascade DataHub is mirroring to itself. Either of these are probably due to misconfiguration. Check your configuration files to ensure that only one Cascade DataHub is configured to be a master in any master/slave pair, and that no DataHub is mirroring to itself.
10.4.	Messages from Excel
	When you save and close a spreadsheet connected to the DataHub and then attempt to reopen it, you may get one or more messages, depending on your security settings in Excel, or other circumstances. Here's a summary of each message, and what to do: This document contains macros. Enable them? Click Enable Macros. This workbook contains links. Update them? Click Update. If the DataHub or Connect is already running, all the links should then update automatically. If not, you may get a `#REF!` entry in some cells, and the next message (see below) will probably appear. Remote data not accessible. Start the DataHub or Connect? Click No. At this point the best thing to do is close the worksheet, start the requested program, and then reopen the worksheet. When you update the spreadsheet (see above) this time you won't get any `#REF!` entries.
