Assembler tutorial HELP ME!!!

I'm trying to learn how to crack programs and change them a little. Now i've got the disassembler "W32DASM" I need to learn assembler. So I wanna ask you all: Can somebody give me (or even write for me) a simple basic tutorial. I know something about other languages: I know nearly everything about VB6, know a little C++ and I'm currently learning Java (JBuilder 5).

So could somebody give or write a tutarial for me? I NEED ONE!

Thanks a lot, Ray2003 (Ray2003_NDJ@Hotmail.com)
