Big problems with my dll.xml file

Have purchased carenado 390 premiere and that have send me in big trouble.

Plane installed fine and flies beautifully but.....the dreaded Database loading in the FMS stares at me. Gone through all the articles on the net about this as well as contacting Carenado support whe i must say came back very fast and I have added the lines in the dll.xml file as per their sggestion and my own findings and Downloaded the carenavigraph .dll file and placed it in the root of FSX

Nothing worked.

I used Wordpad to edit the dll.xml file as i had read that it was ok for this. I have 6 dll.xml files in total 1 active and 5 bak files. Since I have learned that notepad++ is the best tool and have downloaded this.

Now when I copy (drag and drop)  the active dll.xml into notepad++ it looks like text to me but when i do the same with my dll.xml.bak files it looks like HTML to me.

Have i accidentally de-formatted my file perhaps?

Strangely all the applications that should use the dll.xml are working fine ( execpt the 390 premiere) fsupic, Accufeel. orbx, and fsx sdk

This is what the active dll.xml looks like:

Now i am afraid to do anything to my .bak files if the same happens.

I do remember that when after making the edit and saving it said somthing about reformatting or somthing.

Can I just edit the .bak file in notepad and then save it as dll.xml and before renamed the dll.xml.bak or what.

Have used Flight Simulator over  20 years but not the last 5 just taking it up again.....as well as tinkering with files and such.

Hope some one can help
