Leica language issue

Dears,

I wanted to change the lenguage on the programs on my Leica TCRA1103. I used the Leica Survey Office, but I somehow I deleted the lenguage. Now i see $xxxxxxxxxxxxxx lines in the menu, where the text of the menu's was.

The system lenguage is english, and it is ok. However I deleted the application lenguage. How can I add application lenguage?

Thank you!

Kind Regards,

Dani
