Ribbon woes

[ACommandLineKindaGuy]

I've got a workbook I'm trying to modify the ribbon.

I have an empty "test" workbook that I used to create the XML code using Ron de Bruin's and other's examples.

The empty workbook's ribbon is exactly what I want.

Now I copy the XML code into a the target workbook that has all the VBA and features, including the commandbar additions I've entered on the Worksheet Menu Bar

I cannot get the XML code to take hold. The timestamp shows that when I save the XML code in the CustomUIEditor, the workbook is updated. But the ribbon is not modified. I've tried disabling the workbook open event as well as all the workbook/worksheet activate VBA. I've unprotected the workbook and all worksheets. All with no luck.

Does anyone have any suggestions?

I should point out that previous versions of the workbook have worked. But--I cannot figure out what was different with those workbook versions....

Thruly frustrating...

PS. The XML doesn't save--I save in CustomUIEditor; the datestamp for the excel workbook updates, meaning something is being written to the file, but when I reopen the workbook in CustomUIEditor, nothing is there! Working with Office 365 and the excel filesize is 6.7MB
