You might have opened the bot but moved/misplaced somewhere. Meaning it already is running but somehow got moved and it's just somewhere like the hide function.

I have experienced this in the previous versions but not in the current version. Have you guys tried looking at the task manager? How about a restart? It should be there.

If not, try using a restarter bot posted in the bugs/suggestion section under "hang" topic of v4.3:

I used that before.
