Only Acrobat X and XI are currently supported. Acrobat 7 was released in
2005, which in the world of computer software is ancient. And Reader 5 is
even older...
The only currently supported configuration with Reader and Acrobat on the
same system is when both are of the same version, so your problems with
Reader 9 open are very likely explained by having different versions of
Acrobat and Reader, and running a configuration that is too old to even
support both on the same system.
Upgrade to a modern system (and supported!), and we are in a much better
position to provide help.
