If it was that easy to do, no account would be safe. For all intents and purposes, it's not possible.
Are you talking about brute-force guessing the password? And the game is browser-based? At most you're going to get ~1000 login-attempts per second (?) and a 10 character password (a-z, A-Z, 0-9 = 26 + 26 + 10 == 62 distinct characters, 10 places) has 62^10, or 8.3929937e+17 unique passwords; 8 with 17 0's behind it. That's a lot of password guesses. If the password is 12 characters, it's 62^12, or 3.2262668e+21 unique combinations. To calculate the max time it would take, 62^10 = 8e17, divided by the number of guesses per seconds(assume 1000) would make 8e+17 become 8e+14. 800000000000000 seconds. Or 2.5 years.
Using a 'pre-made password file' will cut down the number of guesses dramatically, but chances are high it won't contain the password.
And "programming in batch script" (which is what you're doing w/ that 'notepad code') won't get you as far as learning a real language.
