I installed Panzer Corps 2. But at the menu I clicked on the German flag by mistake. Now the game is in German. How do I get the game to use English.

Dumb question, I guess. What is a DLC?

1 How is Panzer Corps Gold Ed, different from Panzer Corps Grand Campaign Mega Pack? 2. Does Panzer Corps Grand Campaign Mega Pack contain these games: a) Campaign '45 West b) Campaign '44 West c) Campaign 42-43 West d) Africa Korps e) campaign '45 East f) campaign 44 East g) Campaign '43 Esat

I am not sure what Panzer Corps Gold contains. For example Does it contain these Games:
a) US Corps 1944-45
b) US Corp 1942
c) US Corps '43
d) Panzer Corps Soviet Corp
e) Panzer Corps Operation Sea Lion
f) Panzer Corps Allied Corp
