Maybe not speaking your language I can't explain myself well..
For the 15-day trial I installed and used Italian, now the license actually says that I can only use one language, but why can't I use my own that I have to be forced to use English?
A standard Plesk license allows you to use one language pack. You should be able to select whatever default language you want. Doesn't that work for you?
