| Thanks Dale,

| I tried to execute that but I get (from topaz) this error: Invalid
| project registration. Stack below.
| I might have tried to load a first time, which somehow fail and now I
| am trying again...

| Any ideas?

Thanks for the stack ... invalid registrations is one of the areas in the Metacello Preview that might still have issues. I have fixed the known problems[1],[2]. You could have hit one of the old issues or a new one. The following code should clean up any existing invalid registrations: 

MetacelloProjectRegistration registry baselineRegistry values 
detect: [ :registration | registration isValid not ] 
ifNone: [ 
"no invalid registrations, don't reset and prime" 
^ false ]. 
[ 
MetacelloProjectRegistration 
resetRegistry; 
primeRegistryFromImage ] 
on: Warning 
do: [ :ex | 
Transcript 
cr; 
show: 'Warning resumed: ' , ex description. 
ex resume ]. 
^true 

If you see another case of invalid registrations after running this code, we'll have to dig a bit deeper.
