Do I have to reinstall every time I close my Camera?

Somebody told me that once the camera was shut down I would have to reinstall again.
Sounds crazy, tell me that aint so?
Thanks Peter

That someone is not right (or at least, it was a misunderstanding). After the firmware upgrade process, any card with ML will work automatically without any further steps - just insert the card and start the camera.

If it's the 7D I think you have to.
Yes it says here.
