Most likely your templates are just fine. (they will have an .adt extension) however, Word 2013 is not supported and that version of office does not recognize ACT templates. Your best bet is to reinstall Office 2010. I don't believe there is anything wrong with your templates.
You'll also want to check the Word Processor setting in Sage ACT! to ensure it is set to 'Microsoft Word'. This is done through Tools > Preferences... > Communication tab.
This also happened to me but the only templates that disappeared are the ones in folders all those not in folders are still there and the folders are there but they are empty. Do you have a fix for this? When I upgraded to Office 12 I upgraded my ACT to Pro 2013....is there another version I could use to work with Office 2013
