Switched to UE4 now getting errors

I went to make a small update and have now spent hours trying to figure out what is going wrong. The following are the error from the last attempt:

Before this attempt I was getting a lot of:
Warning: Unexpected character in input: '\' (ASCII=92) state=1........ERRORS

Help please.

I just tried to remove all of the check boxes and dropdown lists thinking that was what was causing the issue but now get....

I have reattached these updated files - perhaps you want to look at both sets to see what UE4 is doing. This all worked with UE3 and perhaps I need to switch back.

In Universal Email, Select the option to use one of the email Message templates provided and check the box to Create a file for your email.

This will create an email template file that you can edit directly with out having to enter the Universal Email wizard.

Frustrating last night but that worked. When is it better to use this method? Thanks.
