Problem opening JPeg files ...

Hi,

I currently have 2.6.1 version of GIMP installed on my PC#1, and altough it works just fine with most of files, there is one that I cannot open.
When I receive JPeg files, made on iMac, I cannot open.

The problem is that I have a 2.4.7 version installed on another PC#2, wich has Paint Shop Pro installed too, and it works just fine!

What can I do or install om my PC #1, to solve my problem?

Thanks,
