i-report 3.7.6 error while editing JRXML

I have a problem w开发者_Go百科ith editing XML files with i-Report 3.7.6. My XML file was created with i-Report 2.0.2 and later saved in JRXML format with i-Report 3.7.6. When I click on the XML file now, i-Report gives me the error:

---------------------------

How can I fix this?

Add this text (or similar from another template) in XML mode after <kbd><</kbd>property name="ireport.y" value="0"/>:

<kbd><</kbd>style name="Sans_Normal" isDefault="true" fontName="DejaVu Sans" fontSize="12" isBold="false" isItalic="false" isUnderline="false" isStrikeThrough="false"/>
<kbd><</kbd>style name="Sans_Bold" fontName="DejaVu Sans" fontSize="12" isBold="true" isItalic="false" isUnderline="false" isStrikeThrough="false"/>
<kbd><</kbd>style name="Sans_Italic" fontName="DejaVu Sans" fontSize="12" isBold="false" isItalic="true" isUnderline="false" isStrikeThrough="false"/>

This Assertion means that your fonts are corrupted
