Afternoon nataru...
Almost seven years after writing the
original post, I can confirm, by hitting ctrl+alt+r whilst typing this reply, that it is still working perfectly for me here with MC24.
I've been trying to think why it might be crashing for you, and I'm not coming up with much unfortunately...
With MC open, press win+r to open the windows "Run" dialogue, and enter the following in there...
mc24.exe /MCC 10047
Press "Enter"... Does Play Doctor kick off or does MC crash?
The ctrl+alt+r shortcut is basically sending the same instruction to MC.
Have you confirmed that nothing else is using the ctrl+alt+r shortcut?
Someone, sometime ago, posted a link to an app that listed all assigned keyboard shortcuts and the programs they were assigned to. I tried it at the time but found the results way too complex to decipher. Try closing MC, and the MC server if you use that, and press ctrl+alt+r... does anything happen?
With MC open, and nothing playing, go to "Playing Now". Can you start Play Doctor manually?
Beyond that, unless you have any more detailed info about what might be happening at your end, I'm out of ideas.
