Font issue: Bullet and chapter title disapper

Hi,

I am using FM10 and so my client.

I got a few files from my client to upgrade.

When I open the project "Font is not available" message is displayed.

When I move ahead by ignoring message, font style gets changed, bullet is replaced by "?" and Chapter number is not displayed.

I am new user of FM,kindly guide me.Thanks in advance.

Thanks and Regards,

Rahul
