First of all thank you for your feedback (and for playing)!
Yes.. the combat is not always so smooth to play :(
About the language, there's a problem: When you save the game, the language is saved too (the savesystem is like a savestate).
When you load the game, you also load the language that was selected when the savefile was created.
You should select your language an create a new game :(
Thank you very much again!
