Hi,
This is probably because you have set the launcher to not automatically update.
At the launcher, press "New Profile", name it "Default", and for "Use Version", set it to "Use Latest Version", then save.
From the dropdown at the bottom right, select "Default" and Play 1.7.
In the future, do not edit the "Default" profile unless you have to, otherwise, make a new profile.
