Configuration crashes on startup (4 Viewers)

[KeithP]

I have just completely wiped my hard disk and reinstalled the OS and MediaPortal. I have it configured pretty much as I want now, but suddenly I find that I have problems with the Configuration program. I am getting an Unhandled Exception on starting the config. program, and if I choose to ignore the error, I get another exception on attempting to save any changes.

MediaPortal itself runs fine, so I am not getting any Debug logs to post.

I notice the error is coming from .NET Framework and refers to an issue with an xml file (copy of error text is attached). I had made a modification to the keymap.xml, in order to use 'backspace' instead of 'esc' for 'Previous Menu'. I tried restoring the original file and it has not cleared the error, so I presume my edit is not related.

I'd appreciate any suggestions on how to troubleshoot further.

There is an error in XML document (0, 0). ---> System.Xml.XmlException: Root element is missing

have you edited any of XML files in any editor outside of MP?

 

[KeithP]

As I mentioned in my post, I manually edited 'keymap.xml': I replaced 'esc' as the key for 'Previous Menu' with 'backspace'. But I have now restored the original, unedited keymap.xml and the error is still occurring.

I am pretty sure I didn't make a mistake anyway. Here is the before and after of the section I edited:

ORIGINAL:
<action>
<id>10</id>
<key>esc</key>
<sound>back.wav</sound>
<description>Previous Menu</description>
</action>


REPLACEMENT:
<action>
<id>10</id>
<key>backspace</key>
<sound>back.wav</sound>
<description>Previous Menu</description>
</action>

it can be that you introduced other changes invisible to your editor (like BOM at the file start, or encoding...).
Is the exception text remains same even for unedited keymap.xml? or do you have other error report?

 

[KeithP]

I used Notepad to edit the text, and literally deleted the 3 characters for 'esc' and typed in 'backspace'. That should not have introduced any other changes in the file should it?

I any case the error is the same with the original unedited keymap.xml in place. I am not getting any other errors, other than 'Application Hang' appearing in the Windows event log.

I found an old thread, searching via Google rather than using Search tools on the forum.

It seems that the MusicDSP.xml is prone to corruption, particularly when messing around with S3 Sleep. I have been having problems with my system Sleeping (it keeps going into an unresponsive state) so I have been fiddling in this area. I discovered by musicdsp.xml file was empty, as in the post above. Deleting it has fixed the crashing.
