Aha, I seem to be getting somewhere here.
Strange !
I do not know if in the importance ... is the extension of the LOG file.
Try this:
[Console]
HISTORY=1024
HISTORYCMD=1024
LOAD=console.cmd
SAVE=console.cmd
LOG=1
LOGTIME=1
LOGFILE=LOG.LST
LOGKEEP=0
And please for the safety of your computer asking Windows to display the extensions in the file manager! 
Done what you said thank you SAS~Epervier.
... mine, too, has always been named :
LOGFILE=LOG.LST
May be that's the reason why ... 
Thank you too Mick
Make sure your IL2 1946 CUP folder isn´t read only! Right click the folder and check in properties.
Flying H thank you too. Directory was marked as read only - changed that now. Found log file.
I'm sorry but we want to fuck your ass because you can't find your log 
Just kidding 
LOGFILE=log.txt
so your log file is named log.txt
As said by Moezilla it must be in your IL2 root folder, the main IL2 folder
Phew and there's me thinking I'd be blacklisted as a village idiot.....!
I'm sorry but you will 
Anyway your is a strange problem.
I changed my log file's name years a go, now is log.txt and is there in my root folder.
Try this:
start the game, return to the IL2 folder and check if there is the log.txt file
And OberstDanjeje, I did what you said and guess what - there's my log file. Thank you I've learnt a lot tonight....!

But it looks like this - why?

I've started CUP and viewed "play track" - no problems so far as in CTD. But how do I view logfile that's easy to understand?
And one last thing - why are my "postimage" images so poor - do I have to register with it?
Many thanks for helping - much appreciated
