don't work on circuit, please help

[DonLuis]

Hi you all:
I am from mexico, and I do apologize for my English, so I am new to programming, as a matter of fact this is my first intent, I have learned reading from posts on this forum and consulting the pbp and proteus manuals, the thing is that I wrote this code on pbp 2.6 and simulated it on proteus and works fine so i programmed the micro controller with masterprog (wich is a programmer that I got from Mercado libre, same than ebay over there) and when I put the micro on the protoboard nothing happened, and when I pressed the reset button and tree leds light up (00101010) and stay on and nothing else, I have tried reprogramming and checked al connections over and over again but noting seems to work, I have read many threads on this forum but I don’t find anything that can help, so I really will appreciate if any one look at the code and comment what I am doing wrong thanks very much in advance.
This is the code
