Cannot complete campaign mission 1?

[igor7111]

I tried searching for an answer but came up empty, so I must have
done something wrong with the install.....DW, 1.04 patch, LWAMI 3.05
and the quick fix.

As soon as I start the first mission of the Russian Rebellion campaign,
I get an announcement that the mission cannot be completed. This
happens like 2 seconds into the game, before I can do anything.

Does anybody know what's going on with this?

Thanks in advance.
