You need to look for something that looks like this:
Code:
<Page BackgroundColor="#00FF00" eq2usescomwndcontrols="true" Location="70,535" MaximumSize="1024,1024" MinimumSize="28,28" Name="Hotkey" PackLocation="right,bottom" PackLocationProp="-954/0001,-233/0001" ScrollExtent="394,31" Size="394,31" UserMovable="true" UserResizable="true" version="1.1">
It should be right under the line that you mentioned. make sure it has that version number in there.
