Hello everyone. I have a very annoying problem in Cubase 5. When I connect my digital keyboard to my computer and I select a VST instrument, for example, RealStrat, I can play and record, but I can't load any presets to the VST instrument, as they can be distortion or effects. I also noticed that when I open the audio menu I can't select any option in it. I use Windows 8.1. Here I attach two images of the problem. I really hope someone can help me to solve this problem. Thank you.
