I thank you = [color:"yellow"]Ich danke dir[/color] (I thank to you = I know this is very bad English, but shows the direction better, possessive pronoun IIRC)
but you can say: [color:"yellow"]Danke[/color] (shorter and easier to keep in mind)

Ich thank you for having it in both languages, way easier
[color:"yellow"]Ich danke dir, es in beiden Sprachen zu haben, viel einfacher [/color](yes, I know, this is unelegant German, but I try to stick to the words. Better would be to use "make/making" instead of "having" ->
Ich danke dir, es in beiden Sprachen zu machen, viel einfacher
