RefMan 12 vs MS Word 2010 vs WordTemplate

My organization recently upgraded to Office 2010 and to Reference Manager 12.

We use a word-template with several macros. These macros are available in the tab Add-in. After installing Reference Manager 12 the tab Add-in has disappeared.

If I reconnect to our Wordtemplate the tab Add-in with macros return. If I close Word and re-open word the tab Add-in has disappeared again!

Please refer to the two attachments for a before and after screen-dump of my tabs i word.

I use the Danish version of word, so I apologize for any wrong English-terms!

Can anyone help me?

Kind regards,
