Cannot launch a Skirmish game

I DL'ed CoH:EF and it played fine for a while, until a crash while playing a saved skirmish game.

Now, I cannot launch a Skirmish game at all. The message is 'an error occurred while starting the game'.

When I exit EF, there is a notification that the game is trying to launch in -daemonmode. OK'ing that does nothing.

Interestingly, I also cannot now run a skirmish game on CoH:New Steam Version, either ...

I uninstalled EF and reinstalled it, but no change.

here's my warnings log:

The log says you are playing the old version of CoH. The latest version of EF is not compatible with that unless you add the compatibility fix from our ModDB download section. You might find it very quickly.
