Hi
I'm afraid that you can't run setups from the 1.X series in the 2.X software. There were just too many system wide fundamental changes to make it possible to provide a setup upgrader. All of the Factory Setups were rebuilt from scratch using Workbench, and quite a few things about them are different. We were careful to make the playing experience identical for each of them, but the way that's achieved is different in 2.X in quite a few ways.
Trying to load 1.X setups into 2.0 may well cause bad things to happen, and it certainly won't result in any kind of playable system. I'd expect it to crash in some way in fact.
We did announce this incompatibility in all of our product communications but I've just realised that the current software download page doesn't make this clear, please accept my apologies for that, it should do and we'll change it next week to reflect that. It's been a long time since 2.0 was first released into Experimental, and we tend to forget that quite a few people haven't been following developments during that period.
Could I ask what customisations you'd done to your 1.4 setup?
