hey guys

i know this might sound stupid, but i keep getting this error since today. i couldnt find this error on the internet so i decided to post here. when i got my motorola milestone everything was perfect. i went to study to czech republick for half a year and disconnected my mobile internet. now i am back and i have my mobile internet back, but i cant access the google account. i keep getting this error "your username and password do not match. please try again". i tried to do the factory reset several times but it still not working. i tried to connect my another gmail account and it worked, but this one does not. i tried to enter this one like 40 times, and there is no way i could do mistakes every time. maybe i need to change something in google.com/settings or smth?
thank you for your attention

See if you have the Google 2-step verification activated in your gmail account

If you do then that's the problem. It was with mine after I did a factory reset on my MB508. It drove me nuts for hours until I shut the 2-step verification off on my account and then I had no problem logging into Google or gmail on my android. Once the accounts were added I activated the 2-step verification again and all is well...
