After many years of cubase use, I have a new problem. I can play my midi files in a project but when I try to record it fails. I have Cubase 6.5, and whatever I try with an usb keyboard or with my ESI 8XL midi interface, I don’t get the midi signal to my vet’s. The record button colours red and midi input is right in the device setup, and I use " all midi in", and in the transport you van see the incoming midi signals when playing the keyboard, or the sustain pedal. What can be the cause, and why did not have I this problem last years. 
Who knows the solution?

1.MIDI Filters are set.
2.“All MIDI inputs” is not configured correctly.
