After compiling with pic Basic Pro Compilier using MPlab IDE and with the message "unable to access .COD"Can I still program my chip with the code I wrote.
I don't think you can. Try to check out the help file. I used to have this kind of problem as well, due to some registration problem of the C compiler.
i found the answer to this errors, basically all that is require is to uncheck the all the box except the mpasm box under the build option. This would allow mplab v6.30 to compile the codes using pic basic compilier
