Excel error - "USP Excel template is not valid."

[Kando]

when trying to open a spreadsheet I get the bar that says some content is disabled. when I click the button to enable data I get a message that says "This version of the USP Excel template is not valid. the program will close.". when I click on the close button of the error message, excel closes.

Office 2010
Windows 7 Enterprise
File ext .xlsm

What must be done in order to input data into this spreadsheet?

Thank you

Where you get the template?  Did it previously work for you?  Have you tried other templates?

The template, which is really just a worksheet, was sent from a company branch in Germany. They have sent other sheets in the past with no problems. We have received and sent sheets to branches in the past.

This particular sheet gave the error from the beginning.

I have sent an email to the originator to get the version of office that they are using as well as a fresh copy in case this one somehow became corrupted.

Ok, the sheet was created in Excel 2010, and is trying to be opened with Excel 2010. A new one was sent, and we get the same error message.
