how do you actually download an up date for KDE

[hawley]

How do you actually download an up date for KDE. I have been playing with 
Freebsd off and on for 3 yrs now. At present I have "DSL" internet access. I 
am running a 500 meg Hz intell machine. I have read untell my eyes bleed and 
tryed things untell my fingers cramped: NOTHING EVER WORKS!!!! I am now to 
the point where I would pay to have someone walk me through a successfull 
download. Any thoughts?
