calibre does not detect kindle fire hdx

[Rachelsmum]

Hello, I could use a little help. Brand new kindle hdx. I downloaded Calibre to my boyfriend's computer and was able to save books to both of our kindles. Then I took my kindle home and tried to save other books with the calibre I already had and all of a sudden it doesn't work. Funny thing is, now by old kindle isn't detected either, and I never had a problem before. Is it because I'm using Windows xp? Here's the info for my kindle fire hdx;

It won't
You are using XP which does not work well with MTP drives (no letter) so Kovid disabled MTP mode.
