Don't worry. There's lots of ways to improve at the game. Try giving the M'Hunters strategy guide a read if you learn easily: http://nghood.com/warlight/strategyguide
Most importantly, ask yourself why you lost a game. What did your opponent do better? How did he get more armies per turn? How did he know where you were? You can always ask your opponents how they won. Sometimes people will happily share their thoughts.
Edit: and ignore people who respond with "you're just bad". Everyone started out as a newbie
