Replying to Lightroom won't accept .ARW files from my RX100iii

I'm getting pretty pissed off at this point. I have been uploading files from my RX100III for a long time now with no problems. Now I have a whole series of photos from Morocco and Italy that I REALLY want to upload and edit and I can not for the life of me get LR5 to accept them! Does anybody have any idea?

- It usually reads my .ARW's
- I have tried adobe raw converter to convert to .DNG before lightroom and it won't recognize the files either
- I don't believe it's possible to upgrade LR5 anymore than what I have now (8.1)

Any ideas of file types that they could be converted to without losing the flexibility of raw? Any ideas why it wouldn't be reading the files? Any help would be appreciated!
