It seems that you have not choosen project type "Analog or Mixed A/D". PSpice toolbar get enabled only if the project type is "Analog or Mixed A/D".
When you make a new project i.e. File --> New Project. A Window appears asking for the name of the project and type of the project. Choose "Analog or Mixed A/D" option. Now, you find the PSpice toolbar enabled.
