    7.5.8 Error when trying to uninstall packages

    Anyone can shed some light on this?

    I upgraded a 7.4.8 to 7.5.8 and upgrade seemed to go ok without errors.

    When I try to uninstall any package, under Developer->Packages->Installed

    I get the following error, regardless of which package I try to uninstall;

    An error occured
    

    Object reference not set to an instance of an object.

    EXCEPTION DETAILS

    System.NullReferenceException: Object reference not set to an instance of an object.
