My NoLimits 1 simulator stopped working

Every time I try to open my NoLimits 1 simulator I get a screen displaying the message "Input No Support" on a dark screen. And the message slowly moves around the dark screen like an old-time screen saver, or a game of Pong. And then the only way I can get out of that screen is to shut down my PC and reboot. Not even Escape or control/alt/delete does any good. Does anyone know what's wrong and how I can get my NoLimits 1 Simulator working again?

^ I wish I could give you a hand, but I haven't ever faced such a big problem while playing NL1 simulator. Please forgive me for the fact that I can't be on your side this time though I'm still a NL1 user like you. I have to admit that I'm not a technical person so I should know whether or not, on this forum, there are NL2ers who previously were "skilled" NL1ers.
