I am using the latest version of ZENCART and have recently installed the add customer from admin addon. I am able to add a single customer manually; however even when I select the "Send welcome email", an email is not sent. I do receive the red box which has "There were errors', although there are no errors listed in the box.

I tried to upload the CSV file and I received the following error:
"Could not move file"

Any help would be greatly appreciated.
