Its not too hard, I just downloaded it for a quick look and did it.

set a breakpoint on both messages by searching for string references and pressing f2.

Run the app

*BIG HINT&* (Well i think so).
The program has self modifying code so you might need to look around a little if it isnt there when the app starts up.

i have just got done doing this app, and if you are using Olly, then it will be really easy! it wants you to see what the app does with your name, so in Olly run the program while you decompiled it, and then look in the hex section. learn from how you complete each mission, and dont just do it for the points and bragging rights Wink

Can't believe how simple this one was. Have to love Olly.
