I will fix this ASAP BUT...
Watch out! Until I fix this small bug - you have to create a domain.history.properties file and place it into the OUTPUT_DIRECTORY that you chose for your projects.
The domain.history.properties file can be empty - the CPC will populate it with new domains as you create them. If you want to point to an existing domain you can do that too I have only tested this when the domain folder exists in the OUTPUT_DIRECTORY [you *may* be able to point to other directories using the relative path from the OUTPUT_DIRECTORY]:
In the example below, I created the folder CommonDomain manually -- additional domain folders were created by the projectCreator.
Example content of my domain.history.properties file:
#Mon Jan 14 02:23:33 EST 2008
4=commonDomain117772d0c14
3=commonDomain1175cfa7be3
2=commonDomain1175b13b19a
1=CommonDomain
