There is no such thing as "necroposting" if the case is still relevant and remaining unsolved, unless the OP calls it off, but forgets to close the thread. I think the proper system behaviour in response to a problem is actually to crash a program. Then, at least, there is a clear signal, hopefully some error code left, also one is free to continue using the current session. If the software just lingers in an attempt to proceed but most apparently goes nowhere, it is probably a management issue, which means, the drivers or else tell there is a possibility to proceed but the actual resources or otherwise conditions are insufficient. I had similar problem trying to run Outlast without a hacked GPU - that is, with mostly disabled dedicated GPU. It could be the sort of compatibility issue, perhaps. Maybe in your case it was waiting for some network validation which never came.
Just some loose intuitions.
