Hardware simulation and other setting in control builder gets overwritten while you do an upgrade / update to 800xA System Version.
Re-do the settings and you should be able to perform simulation.
1) Open ControlBuilder
2) Open Tools -> Setup -> Station -> Application download
3) Change "Hardware Simulation Allowed" to "True".
