Aperture don't read my video .mov anymore, it did'nt import them too!

i see movie thumbails in aperture but a click on it give me an empty gray screen...

if i look in my aperture library (right click) and perform a search on .mov type i find all my movies...

strange it seem's that aperture is now unable to read .mov.... (>_<)

have you an idea?

Thanks... for your try to help me... it seems that timemachine backup is the guilty... the right way to got the movies back in aperture is the following...

on Macosx LION

1 - reboot and maintain cmd - R

when the menu prompt you to choose what to do

2 - select install macosx LION

3 - enter your apple ID

(the F.......G language selector flag is on the upright at the screen i see it after on my 27" why do you have made so little? do you imagine how hard it is to tape password and name in qwerty when you got an azerty keyboard... shame on you)

4 - wait the job to be done

5 - your mac reboot and work

Now aperture seems to work correctly, i can see the movie on my canon EOS 7 and import them, all the old movies are back
