Dotfuscator linking problem

[Fred]

Is there is a better newsgroup for this question?

I am having a problem linking assemblies into one using Dotfuscator
Pro 4.0.

The problem occurs when linking the following into one exe:
program.exe
A.dll (references C.dll, but was built when C.dll was versioned 1.1)
B.dll (references C.dll, but was built when C.dll was versioned 1.2)
C.dll (current version, 1.2)

When I run the program, I get an error saying "could not load assembly
version 1.1", and the opposite happens if I try to link in version
1.1.

Here is the actual output:

System.IO.FileNotFoundException: Could not load file or assembly
'UltraScan.Common, Version=1.20.3120.26421, Culture=neutral,
PublicKeyToken=null' or one of
