Sorry, I don't check the Comments very often (there's no notification and I don't remember to always check every mod).
Notepad is fine to edit, but the lines cannot simply go at the bottom of the page.
You'll want to place them above the line at the end of the file: </Page>
So that it would look something like this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<Page IgnoreTab="false" ismodule="true" Name="Custom" PackSize="1,1" PackSizeProp="0002/0003,0002/0003" ScrollExtent="1024,768" Size="1024,768" Visible="false">
<include>eq2ui_custom_infocenter.xml</include>
<include>InfoCenter/includes.xml</include>
</Page>
* Note for the future: There exists an InfoCenter topic for support questions like these. On the download page, there is a link directly to the topic.
Also in yellow text at the top it states to post any issues in said support topic. Hope you get it working
I updated the instructions on the page so that future browsers will more precisely see how the code should look
