Impossible issue...

[ForeshadowedDawn]

Just set it to download custom content.

Subscribe to all content packs that FL has.

Also, you can't open GMA (addon file) with Winrar.

Okay, I subscribed to all of the packs and just waited on the main screen for them all to download and extract. When it did that, I tried to join but it got stuck on that boatengine audio file again. I have set it to not download custom audio, and now it works.... ish.... it just says not responding now, while saying "Workshop Complete". I left it for about an hour... still nothing.
