If you can edit your journal widow with note pad you can fix it. You need look for the FIRST line and make SURE that is has Version="1" in it. Here is my line #1 from journal_quest.xml:
<?xml version="1.0" encoding="utf-8"?>
<Page Activated="true" eq2usescomwndcontrols="true" Location="42,150" MaximumSize="1600,1600" MinimumSize="350,250" Name="JournalsQuest" PackLocation="left,top" PackLocationProp="0042/0001,0150/0001" ScrollExtent="621,250" Size="621,250" UserMovable="true" UserResizable="true" Version="1">
That whole line of course is ONE line in the notepad editor.
The key is the Version="1" at the END of that line BEFORE the >
This will fix it.
