please respond someone, i've purchased the script and expect support from authors!

I have made a partitional estonian translation.

I have a small problem. This file is in correct spot and when someone purchases something from my webshop and language is set into enstonian then client recives invoice in english not in estonian! I have multilingual webshop!

Use customer language is set YES and Frontend open in current language is also set YES?

So whats the problem?
