Combo Maker Tool

Hey there!

I am looking for a good combo maker tool that is simple and not overly-complicated

i have searched everywhere on the internet and have downloaded multiple executable files and applications

and i cant seem to find one that isnt extremely complicated to use, isnt there anything where i can simply load a usernames.txt file
then a password.txt file and the output is both usernames and pass example (User:Pass) any help would be greatly appreciated.

I have one that works just as you asked.

Here's one I released: http://www.mpgh.net/forum/showthread.php?t=912984
