I have checked, and the Archive.exe is in the CoH2 directory, the map name doesn't have any illegal characters, and neither does my PC name, the PackageBuildFile.txt is also in place. I haven't touched WB in roughly a year, but I never had this issue. The only major event between then and now when I cloned my C: drive to a newer and larger drive, although CoH2 is on my D: drive. As far as I can tell, everything else works although my sound mixer randomly reset a few days later (programs that were muted started playing sound again). I've tried the obvious verify installation, but it did not help.
There is an error when first launching Worldbuilder, but I don't know if it means anything. I don't recall if it was always there or not.
