exporting from chief 9.5 to X1

[Seascape]

Hi Guys,
I have just recently upgraded from 9.5 to X1 and am having a few issues. Firstly I have exported a plan from 9.5 to X1 so I can PDF to someone, then I forgot where it originated from and worked and saved it in X1. Now the layout I have is not the right size on the page, it is alot smaller. Also when I get into the elevations they are not all there. Have I totally stuffed this job and need to redraw?
Thanks for any help, Keep it simple, I am a basic user!!
