This happens when there is a non-alpha-numeric character in your name or addresses.
Remove all non-alpha-numeric characters and the continue button will light up for you.
For example:
Jon Ezra Jr. should be changed to Jon Ezra Jr (removing the . after Jr)
Mical F. Lior should be changed to Mical F Lior (removing the . after the middle initial).
Also, remove the # in apartment numbers and 's in names.
121 Turbo Drive Apt. # 21 should be written as -121 Turbo Drive Apt 21
De'Angelo Jesus should be written as DeAngelo Jesus for the continue button to work.
Please respond to let me know if this helps.
