I think it should just be bf1942\levels\Operation_Goodwood-1944 with no other folders before it. The way I do it is just to put the map on the desktop and pack it from there.
Steinmannit packs from this C:\bfdev\bf1942\levels\Operation_Goodwood-1944 thats correct right? Cheers for you're help so far guys
If you're using winRFA, you should have,
Source Directory: c:\bfdev\bf1942\levels\Operation_Goodwood-1944
Base Path: bf1942\levels\Operation_Goodwood-1944
If you're using Editor42 to pack it, then I'd recommend winRFA. I try to have Editory42 write-to-disk as little as possible because of the problems Dime mentioned.
