Either the file is not a valid xml file..(something have modified it)
or you do not have permission to read it
or something is blocking MC from reading it (AV/Security software/Sandboxing)
But previous version worked without any problems! Update "killed" MC
No the update do not even change the config file. So something else must have done something.
You should not pack xml files.. they are text files and need to be that. Packing them will corrupt them
I packed file to have ability to restore them if deleting would not solve the problem.
Fine as long as you unpack when your restore them
And you should not delete the file under program files since that is the "default" file, That file is never change.
But MC suggests to delete that files! You have to change warning messages.
If the file is delete it will generate a new one. if it can.
I have one more computer running version 5.5 build 1975. I updated it today, and got the same problem. App worked till update. Now it says the same and couldn't start.
It was absolutely different PC with different config and different apps installed. Only OS was the same - Windows XP SP3.
Thanks God I made a backup. I restored previous version from backup (5.5 build 1975) and all works again without any problems!
So it is MC problem.
Sorry. I do not think so, upgrade is replacing some files but not the config file. And if that was an issue everyone should have and issue and not only you
Question is why this is only happening to you. What is unique with your setup ?
The problem is because either the file is corrupt or something is blocking MC from reading it.
You can validate a xml file If you open the xml file in IE, it will complain with an error if the xml file is not formatted correct.
The other is if something is blocking MC. and that can be AV/Sandboxing or other security software.
