Challenge of Reverse Engineering

Hi, this crackme is from the SnD site, and I'm wondering how I'm supposed to input the serial into the program. When you run the program from Windows, a message box immediately pops up saying "The password is incorrect." When you press the OK button, the program exits. So I assume this is supposed to take input from the command line, but that doesn't seem to work either. Could anyone help me out? Thanks

I've created an ASProtect 2.1 UnPackMe set. There are seven files in all, each one using a specific protection option in ASProtect and the last file uses all protection options enabled. UnPackMe_ASProtect2.1.a - Resources Protection UnPackMe_ASProtect2.1.b - Anti-Debugger Protection UnPackMe_ASProtect2.1.c - Checksum Protection UnPackMe_ASProtect2.1.d - Protect Original EntryPoint UnPackMe_ASProtect2.1.e - Emulate Standard System Functions UnPackMe_ASProtect2.1.f - Advanced Import Protection UnPackMe_ASProtect2.1.g - All Protections Enabled I thought it would be interesting for some to examine...
