every thing you need for meterpreter is included in metasploit3. yopu must reasearch the commands as the are separate from metasplot. when the dll is uploaded correctly and you choose to open interaction with the victim type "help". If you are trying to make a custum module you must code it in Ruby. why are You uploading the meterpreter just to gain a command shell. try win 32/reverse_bind_tcp. Try uploading netcat and then excecuting the commands to activate it to listen. This is a much smarter attack vector as it leaves you a back door. I canot stress enough this is for legal porposes only because using exploits with out knowing what your doing and cleaning up after you self is a sure way to gain a prison cell.
