Cannot Open a MIDI editor 7.5.10

Has anyone else had an issue where the whole program hangs upon the attempt to open a MIDI editor? And why can’t i go back to Cubase 7? Why did Cubase 7.5 remove the .exe from the programs folder?

Any help as quickly as possible would be really appreciated.

Ok, I will correct myself, Cubase 7 is still there. But I still cannot open a MIDI editor in 7.5. Can anyone help?

I’ve a PC w/ a I7 processor and running windows 7. Any other info needed?
