What kind of cert did you buy, you need to get one that will allow you to do both your host name and your normal domain.
Ie... host.example.com and example.com
some certs do not support host certs (there is technical name for them but i dont remember it right off)
also remember that some certs if you do it for www they will support www and without www, and some dont. It depends on how cheap you go and where you get them.
i know you already got yours but:
Be sure to ask before you buy, ask and ask and ask some more if you have any questions, because once you buy them thats it your stuck with it.
If you let me know if you are on shared or dedicated i will get you some information on things.

DONT FORGET TO CHECK THE BOX UNDER YOUR URL SO YOU DONT END UP ON THE LIST.
you basically will get the lock if you dont have any images that are not https, if you have the right cyphers listed, if your site passes security checks for stuff like poodle and others, and there are more rules that follow.
google ssl padlock and you will find info on that.
