Error Check in repository PowerDesign v16.1

Hello , I'm trying to do the check in a data model in the PowerDesigner repository but he's showing me the following error:

" Checking out the document ' ORACLE Version 11g '

- Closing the model 'C: \ Program Files (x86 ) \ Sybase \ PowerDesigner 16 \ Resource Files \ DBMS \ ora11g.xdb ' ...

- Checking out the repository document ' ORACLE Version 11g ' ...

- Saving the document location 'C: \ Program Files (x86 ) \ Sybase \ PowerDesigner 16 \ Resource Files \ DBMS \ ora11g.xdb ' ...

- Closing the checked out model ' ORACLE Version 11g ' ...

The document Has Been successfully checked out .

Can not compare the local and repository models . Use the baseline option to check in this model . "

What can this be?

Thank you
