Language according to domain

Hello,
I am experiencing some troubles while setup different languages for different domains.
First of all I have created 5 subdomains: es.domain.com, fr.domain.com, de.domain.com, ru.domain.com and lt.domain.com. The path for them was set the same as my shop path. Then I created 5 additional stores and set different languages for them. Afterwards I rewrote language module simply to put links. But what I have right now that only few languages actually work. For example in english and in french version I see the same "Shopping cart"name (I am not talking about categories and products since they have to be assigned to every language).

Website : horoseto.com

I would appreciate if somebody could help me.

What I currently found out that when I disable cookies languages works perfect.
Now I would like to figure out how to disable language cookie writing and if this wont affect page.
