Invisible Reference pics

Hi,

I have a problem with the x64 V1R3.1 on windows 7 pro 64.

When I try to insert a reference picture, i can only see a black rectangle. I haven't that kind of problem with the 32 bit version.

The only solution I found is to insert a paintbrush object, open the pic i need, copy it in the paint app and save it.

How can I manage to fix that and simply choose to insert a refecence pic  and of course this using the x64 version ?

Rgds,

Regis.
