Have a ticket in from earlier in the day. As was suggested I removed the file , That didn't help. So I uninstalled Ecart 4.1.5 . Downloaded the latest ecart 4.1.5 and it won't install through the extension manager.
Yes I have used it previously without problem. I tested it using paypal and transactions completed fine.
if I need to uninstall anything else, in what particular order do I install them?
