When I try to start the demo, it loads up to a gray screen and locks up there. It doesn't stop responding, according to task manager, though.

Mine did that, but when I pressed Ctrl+Tab, I discovered an error screen, check if yours has one?

Yeah. It goes as follows:

An error occurs in the program!


File:
> DirectX9\C++\DXResource.cpp (482)
CHECK_D3D_RESULT: D3D ERROR : invalid call.

General Protection Fault:

Hello Contaika,

Thank you for posting.

what is your complete configuration please?

What do you mean?

He means your computer specs, like operative system, ram, processor and graphic card.

Ah, okay.
CPU: AMD Athlon II P320 Dual-Core Processor 2.10 GHz

3 GB of RAM

Windows 7 64

graphic card: AMD M880G with ATI Mobility Radeon HD 4250

Oh, seems like you have the same problem as me, FredBrach told me the game is not compatible with my ATI. But lets wait for him to reply, I don't know if thats the problem.

Ah, alright.
Shame if it is, the game looks pretty fun.

Indeed, Fred said they are working to fix the bug, so I'm waiting. At least I can check the game files, and watch vids and such.
