I'm trying to import asset data into Service Desk Plus 11.1.0 Build 11126

I had a template csv which had a single asset listed with an acquistion date of 03/09/2016

That imported fine and then I deleted the test asset.

I then obtained a list of assets to import which all had an acquisiotn date in the same format but when I try to import, I get a bunch of errors such as  Unparseable date: "01/01/2015" in the error results.

I went back to try my test file and that now fails with the similar result Unparseable date: "03/09/2016"

I've tried converting it to yyyy/mm/dd format but still an unparseable date.

Any suggestions? Thanks.
