FirstClass Mobile App - How to get it on my Z10

Good morning. I have a Blackberry Z10 which I love except for the fact that I can't get my work emails on it. I had no problem adding the email when I had the BB Curve, but for some reason the Z10 won't let me add it. My school district uses FirstClass. I have tried to download FirstClass Mobile onto my Z10, but the site keeps telling me I have no devices. The only way I can register my Z10 as a device is through Google Play, which of course I can't use on my Z10. Any ideas?

There was another person having this issue.... at the time FirstClass only had BBOS Apps and was not supporting BB10. And the Andorid App would not work - and may never work.

But in another thread someone tried setting it up as a POP email account http://forums.crackberry.com/blackbe...1925-a-901663/
