@MiniKiller & R'as al Ghul:

The FAQ and trouble resolution is in the official thread of RomeMod:
http://totalwars.net/forum/viewtopic.php?p=45336#45336

In brief: a lot of settings make the demo hang, due to its limitations (lack of some file, positioning over a forbidden position in the map, etc). As Orda Khan says, a lot of times you get error messages about missing textures or other files, and you press Enter.

Sometimes, you don't see the errors but they are there, so you can press Enter blindly anyway. The Demo itself don't hang out your PC, you don't need to press the reset button: keep the RomeMod open, start the Rome demo; if you get stalled, press Alt-Tab (even if you don't see visual feedback), alt-enter. That should maximize the RomeMod window. Alt-enter again shows you your desktop, and then you can open task manager and kill rome demo withouth resetting your pc.

Other common failure is when the Rome Demo is under a very long folder (depends on windows language), so it's better to have the Demo installed as C:\Rome Demo, for example.
