I have just unzipped moose_suite_6_0 on my windows 7 system. Built a model with about 3200 classes following content at http://www.themoosebook.org/book/ . 

When i run the following from the playground tab - [|]

     self select: [ :each | each isAnnotatedWith: 'Deprecated' ] 

I get the following a popup with title 'MessageNotUnderstood: FAMIXInvocation>>isAnnotatedWith:'

the first entry has 

     FAMIXInvocation(Object) doesNotUnderstand: #isAnnotatedWith:

the Variable tab has 

 self "a FAMIXInvocation #noname#Restrictions.eq(""userName"",userName).ignoreCase() (Invocation)"

self

 thisContext "FAMIXInvocation(Object)>>doesNotUnderstand: #isAnnotatedWith:"

self

Can someone help with this? Earlier this used to work(even model building had tons of error/warnings). Now the model builds with much lesser error but cant do anything with it !
