First off, I'am no techie. I did'nt grow up with this, but I'am trying. I just bought a new razr cause i was sick of waiting for the nexus prime. I cant get the thing to sync with my computer so i can check my e mail on the fly. The message i keep getting is "Invalid Credentials" This after entering all the correct info requested, like user name and e mail address. Can someone steer me right please?
