Every session i have played in the past week or so has lost me money. I play strictly by the starting hands chart, i read and reread all of the articles and yet i go to the tables and end up losing contantly.
whats more, im loosing with generally good hands.
From a sample of app. 4200 hands, i have lost a total of $4.5 playing KK and $1.2 playing AA.
How can i fix this before whats left of my bank roll is gone?
4200 hands is nothing. If you are not sure just post some hands in the handjudging, it's very learnfull ;).
Charts are far from optimal but just a basic guide 
I suggest posting your 5 biggest losing hands into the hand evaluation forum and see where/ if your going wrong.
might also want to check your winning hands aswel, Just because you win a hand doesnt mean you played it correct.
Also, as already mentioned, your samlpe is very small
