Compatibility error message

Hi,

I have just installed Adobe RoboHelp 8 on my computer. My colleague sent me a copy of the company's

help file and although she has created the file also on version 8, the following error message is displayed when

I attempt to open the file:

This project is from a newer version of the program. This project no longer compatible with this version.

Please make sure you have the newest version installed.

Once again, both my colleague and I have the same version number.

Are there certain project settings needed when sharing files? How do I resolve this issue?

Thank you for your assistance.

OKaye
