Wierd moment from Steam... Help

So I was out of town buying a present for my Mother for Mother's Day. I come home and go straight to playing Minecraft. My mom comes in saying Valve charged her for a something that was $19.99, so I go check my steam account, remove any info from payment methods and change my password. I check what the item is and it's the RS11 that was in my Wishlist and now is, for some reason purchased and in my collection! Only one problem it doesn't work. I check, it's in my collection but there is no folder in my railworks folder. I'm not sure if I should be happy or scared that it purchased itself, but can someone send me the files? Here is proof I have it. (Still don't know how I got it being that it wasn't there before I left.) This is the one from Steam.
I will PM you my E-Mail.
