Error with Header #5, E-mail game

[Basic Wiring]

E-mail game Error: Message read: "Error with Header #5" when I try to load up the e-mail file sent to me from my French opponent. Will not load. Any idea what gives? Thanks. (Alexs solution (i.e., wrong version compatibility) worked! Once I downloaded the 1.12 patch, I was in business.
Thanks!

Hi Basic Wiring,

This error indicates that you have a versioning issue. Make sure you have both patched to the latest version, and that you have installed the patches in order (including the big one) because they are NOT cumulative!

If you have any further problems with this, shoot me an email at support@ssg.com.au

Regards
Alex
