Alpari UK has MT4 demo with no expiry, other Alpari locations may also.
Forex Liquidity LLC, US also but they sometimes stop the feed to fiddle the charts.

Mig Investments is Swiss, they offer MT4 Swiss etc based account options, might be worth a comparison to US $/pip payouts.. Just got the expiry warning so don't know yet if it will actually expire. Swiss account might be less volatile than US at the moment, but it works both ways. They seem to pull the same tricks as all the rest, figures.
You can also dl MT4 from the manufacturer, Metaquotes and there is a support forum.
