I am afraid that the only option is to upgrade your (ancient) version of OpenAccess to a newer one what has the required patch.
version with patch is 2012.3.1012.1
. Patch is attached as zip file.
version is 2013.3.1211.3
. Patch is attached as zip file. Classic mapping tools are still available in Visual Studio 2010, 2012 and 2013.
If you are concerned that the classic mapping and API are gone, I believe that you can safely use them in the recommended version. If you have already experienced any issues with the runtime behavior and the API, please share them with us.
