Black thumbnail CR2 files ( RAW )

[Kvisten]

Hi I`m new in here. I am from Norway so please excuse my english .
I have got a problem in PSE 4 Organizer.
When transfering my pics to PSE organizer all the CR2 files ( RAW ) gives me a black thumbnail.
I have never had this problem before - it just popped up about 2 weeks ago.
I can open the file in Edit
I can read Exif data
but the thumb is black
and its only when i shoot Raw files.
i have reinnstalled PSE 4
I have reconnected my files
i have checked memory
nothing helps.
Anyone out there been into this thing `?
