I'm new with MIE2 but find it to be very simple to use, but it's full of other issues. It seems you can only upload a week at a time, week 2 is replacing week 1. I could live with this (sort of) if the other issues did not exist.
Can't re-edit and save a template.
USB import doesn't work. My workaround was to copy and paste the template files into the MIE storage folder on my hard drive. Restart the program and the templates were there.
