AOS - Edit in MS Office is failing

Hello,

I have setup the new Alfresco Office Connector in Alfresco 5.1 and am having a an issue with using the Edit in Microsoft Office link. When using the link the Office application opens and then gives an error that the document is not valid. However, if I open the aos folder directly within word I can browse to the file and open it.

I did not find anything in the documentation that indicates I missed a configuration setting. And the forums don't seem to address the new 5.1 version with the Office Connector.

Any hints as to where to look for this issue?

Thanks,
Ron
