The first part of the message given when a network connection is unavailable should be changed as the grammar is currently incorrect.  At the moment, it says:

<span weight=\"bold\">Network Connection Error</span>
Maybe no Network Connection available.
Do you want to store this report until a Network Connection is available?

I'd suggest something like the following instead (perhaps there's a standard message in other utilities that could be adapted?):

<span weight=\"bold\">Network connection error</span>
An error occurred with your network connection while sending the report.  Please ensure that the connection is available and working correctly.
Do you want to store this report until a network connection is available?
