Did you know how works GitHub ?

Sorry about that. I guess, I downloaded via zip and may have corrupted.

I used git and it has downloaded completely.

One issue is, you have commented/removed import Parse, but used PFUser in Register Controller and there-by causing issue.

Maybe this happen because you need change some codes in your app.
Because Sergey use "specific" link key for parse(parse that him configured for he).
sorry for my terrible english .. :)

Try watch some videos from blog and youtube to see how change this... remember to "like" the video :)

Thanks
