I am unable to run any simulations using PSPICE for TI

1. At start up PSPICE displays the message that it is downloading TI Libraries but then shows a message that libraries cannot be downloaded.

2. When I attempt to start a new simulation or edit and existing simulation the program crashes and displays the following message

I think the problem started when I loaded a model for an encrypted part RHFL4913A voltage regulator from Renesas
