Yeah, same problem here when playing as DE.
When starting Belgium 1939, I get this error:
Inherits operations from DGen\ops_WFBelgien1939.dat

I was getting another error before this, about two files (WF_BelgienRed0.mis and WF_BelgienBlue0.mis) missing. There were some files without the 0 in the name, so I copied those files and renamed them to the missing file names. I don't know if it's ok or not, but it's not giving me any errors about them now.
For Belgium 1940 I get
Can't open target file to copy:

For France 1940 I get

Etc. No mission works for DE. All with beeps.
GB and USA missions seem to work, although I didn't play them all yet.
Thanks for your work.
