MasterThemeSchema.xml file has invalid data error when customizing layout

The MasterThemeSchema for our RoboHelp 15 project seems to be radically different from the file sample you posted. My file is generating an "invalid data" message, and the file itself appears to be truncated at the end (stops in the middle of a variable description). Would you be willing to attempt a repair? Might not be enough to work with. I have no idea how much of the file was corrupted (I am not a coder). There are a bunch of group statements at the beginning, and then a LONG list of variables in this format:

<variable>

<name>filter_selected_image_checkbox</name>

<uiname>Active checkbox</uiname>

<type>FILE</type>

<value>filter_mark.png</value>

<group res_ID="ID_GROUP_FILTER"/>

<visual_properties height="10px" left="10px" top="213px" width="80px"/>

<description>The image shown before an active filter when you use the checkbox filter type. Use a square image for best results.</description>

<default-value>filter_mark.png</default-value>

<allowedvalues/>

<sources/>

</variable>

This is how the file ends:

<variable>

<name>filter_unselected_image_checkbox</name>

<uiname>Inactive checkbox</uiname>

<type>FILE</type>

<value>filter_nomark.png</value>

<group res_ID="ID_GROUP_FILTER"/>

<visual_properties height="10px" left="10px" top="251px" width="80px"/>

<description>The image shown before an inactive filter when you use the checkbox filter type. Use a square image for

Thanks for any comments. It would be helpful to me to know how to use the file you provided. Is it intended to replace a corrupt file with a "fresh" template? Or does it define all the primary file areas/components? As I say, I am not a coder.

Yes. I found someone else with the problem and Adobe suggested not working with files over the network, so I'll give that a try. That's a disappointing response because in our work environment, we do not store files locally (for backups, accessibility, etc.) so I'll have to copy everything to the network.
