The only "solution" that I have is to start FSX, choose a default aircraft at any airport. Once the sim loads, choose the JS4100. Hope that helps.

You should be able to turn it on when you have the battery buses hot and the avionics buses hot. If it is not operating in these conditions you may have an activation issue. Try these steps. Uninstall, Install J4100, start FSX and load up J4100, close FSX, Install SP1 for J4100. See if that fixes your problem. If not, contact PMDG, their support is great.
