crash when no internet (and not yet registered?)

[PetrBodnar]

We got crash in our app.
Crash occurs after we install app , trying to run it, and wi-fi is off.
If we turn wi-fi on, then there is on crash. And after that, if we turn wi-fi off and launches our app, there is no crash.
So we think it can be related to Register
