The version of Acrobat that I use (v7) exports files that will open with

V5+ by default. It can export to V4 but I guess that most people 
wouldn't change the default settings.

=========================
Further reading indicates that major changes occurred from Adobe Acrobat
v3 to v4 and everything from v4 onwards is compatible, maybe aside from
a few interactive features introduced in v7.

Having opened the pdf's in question in Photoshop v7 I am presented with
a password box so the problem is not with backwards compatibility but
with security settings that have been applied at the time of creation.

Plain text files would be a whole lot easier than this carry on!
