Log-in help please???

it took me a little while to set it all up on both my android phone and my pc as i couldn't get them to find eachother, In the end i set it up manually through the RDP settings and now my android phone finds my pc and recognises that i am using windows 7 ultimte etc...
now the problem i am having is every time i try to connect it tells me that my username or password is incorrect, on both set up screens i used my googlemail email address and password, i done the same when i went through the RDP manual set up in the username i put my Gmail email and in the password i obviously entered the same password, no matter how many times i try it just refuses to sign me in and always says my username or password is incorrect.

is there something i have missed or done wrong??? please any help or info would be much appreciated, if you need more detail then please ask away  thanks in advance....
