How to change the \"calendar\"? (BattleTech)

Hello. Understand that the accordion, but I only now decided to play this igrulinu. Question I have 2:
1. How to change the calendar? The one that shows the week number and day number. I want to show the year month and day.
2. In files are the fashion furs, I tried a couple (Thor and Mad Cat), but apart from endless download the fight got nothing. Modtek 0.73, the game pirates (Hatabych) 1.7.
