.cmf and .cem ???

[Bert Blitzkrieg]

I have downloaded some scenarios fro CMBB. They have a .cfm extension and won't work on my machine. I have renamed one to .cme and it works. What's the dif?

Dnepre River Crossing. The scenario selection screen says 3 turns. Playing the scenario says 15+ turns. The Blitz say 45 turns. What's up?

Thanks.

.cfm doesn't ring any bell, but .cmf is the extension for an operation, where .cme is the extension for a 1 battle scenario.
I advise you to rename the file with the .cmf extension and look in your "operation" screen. Perhaps it is a 3 battle operation of 15+ turns each ?
