I also noticed in your code (your XML file) that your path reads as
Code:
<?xml version="1.0" encoding="utf-16"?>
<InternetPortal>
<BrowserExe>\ProgramFiles\OperaMobile10\Opera10-armv4i.exe</BrowserExe>
It should be
Opera Mobile 10 instead of OperaMobile10. You forgot the spaces which is why you are getting the "Cannot find file" error. Check the path again properly.
