550D Card Freeze after Shot and Camera Freeze

[Alex1980]

Hello Guys,

i have installed the latest ML Version for my EOS550D on Saturday.
Take some pictures with the very beautiful Software and i take a look to the great option screen that impressed me.
Take several shot without any problems...
On Sunday morning , i take to shots, but bad...photos not saved on the 8GB SD Card.
The Red Light was steady on and the only thing that i can do was to take out the battery and reboot.
After that, i take another few shots without any problems, until i have this issue back.

The second problem:
If i switched the Camera from off to on , the screen was still black= so camera Cold.
Battery out and in solved this.

So, at the evening i put ML off from my SD Card.
Found that verry bad, it seems that ML is the best add-on for Canon user..... if it works

Greetings
Alex
