--- Comment #20 from Esme Povirk madewokherd@gmail.com --- Well, it's still failing to start up. The way we fail to produce an IProfferService instance doesn't raise any exception, so those catches have no effect, the actual exception is never caught, and the end result is that Form1_Load is interrupted before it can really do anything.
That method is here: https://github.com/opentween/Tween_CodeRepos/blob/2fbfaabb01f611fd8433d7425a...
While it is technically possible to dismiss the error see a form, without any of the initialization, it'd be surprising if any of it actually works.
