Hello Mr. Brooks,
Please look at this FAQ for databases migration:
http://www.graitec.com/en/FAQ_view.asp?FAQID=966&Language=EN&Name=How+are+user+settings+migrated+to+a+newer+Advance+Steel+version%3F
If After the migration you still not able to see the template (list), we can force an export, if you still have the databases and AS 2010 installed. Please look at the attached print screen you will recognize the interface of AS 2010 BOM.
If you uninstalled AS 2010, you can also send us the AS 2010 database and we will do the extract for you.
If you had completely lost your database, you must create a new list. In this case you can always call your support to get assistance.
Best Regards,
