As a heads-up: several uses reported a problems with downloading the MCUXpresso IDE setup/installer program.
If pressing the 'Download' button, you might come back to the login screen (to log into your NXP user account):

The likely reason for this is that your NXP account needs re-activation. You should see a link to open a SR (Service Request) which you could use.
Otherwise post a comment here so your account can be re-activated.
I hope this helps,
