Accidentally launched DW 2017 instead of DW 2015, have errors

I accidentally launched DW 2017 instead of DW 2015, force quit DW 2017 before load finish and am getting the following errors:

"While executing onLoad in Design Notes_onOpen.htm, the following Javascript error(s) occurred:

In file "Design Notes_onOpen": onOpen is not defined"

"The following translators were not loaded due to errors:

OAWidget.htm: has configuration information that is invalid."

How do I fix this?

Thanks,

John
