Can you crack the code?

Crack the Code and then leave your own Coded message. Whoever can crack that may leave the next one:

yjod djpi;f nr tsyjrt do,[;r og upi yjoml snpiy oy/

jsbr s hp smf yjrm ;rsbr upit pem vpfrf ,rddshr gpt dp,rpmr r;dr yp vtsvl/

That one shouldn't be too hard at all.

I'm hopeless at that kind of stuff. I have a hard time with plain simple English!
