how to find an email from someone aim screen name..

If anyone out there could help me I would greatly appreciate it. You see I want to find out who has been sending me messages under a certain screen name because the person I say it is says tht it isn't them. I want to find out their email address or perhaps the ip address but don't know how. so once i know the ip of the screen name i can find out the ip of this person tht i hate and if they match then i know she is a freaking liar just as i suspected... if anyone can tell me how to do taht or help me out, it would mean so much to me.. please i hope someone has an answer..

To find the IP address of somebody on AIM, just Direct Connect with them, and open up a Command Prompt, and type netstat -n, there IP would be the last on the list.

when i did this, a box popped up but quickly went away..like a ms-dos screen but it was real quick then went away..

In order to make the command prompt behave correctly and not dissapear right away first go to start -> Run -> type in cmd -> once at the prompt type in netstat -n

oh thank you..how much do you know about this stuff and computers??

I've just been around computers a lot. I am also studying for the A+ Exam, and google is a big help for troubleshooting problems.
