I think thats your problem. Everything I find on that error code seems to point at a problem to do with Micorsoft Exchange Server and HTTP Requests for XML files. You may want to look up some info for that error code (0x80040111) to see if you can find a fix for your COM component, Exchange itself, registory, IE Version, ect...

What version of Paint.NET are you running, If its older then 3.36 then you may want to try uninstalling Paint.NET, and download the new version and installing as it could be a problem with your Paint.NET trying to find and download update files. I believe you are on 3.36 as I am sure I saw it in the crash file. You can also try turning off the update options for now.
Could even be a problem with System.Xml.dll, if this is the case you should do a repair of the .NET Framework.
