Adding/importing FB albums can be a nightmare. Album lists don't propagate. What worked yesterday may stop working tomorrow.
Even if you have success adding an album, download times are horrible. This is a FB limitation, but is so bad you will not want it on your site.
IF YOU STILL WANT TO GIVE IT A SHOT....
When you purchase the pro version, you are sent an email with a download ID. DONT LOSE IT, because it is the only way to download upgrades. Logging into your account is not sufficient to allow you to download the program.
Plus, even though you are a registered owner of the Pro version, they dont bother to let you know when an upgrade is available.
Forget support. Like others here have already said, it is horrible. The first response to your question will be a week away and will simply ask for your order ID. (Did I mention you need to keep that handy????)
Bottom Line...your life doesnt need this kind of stress.
