Jaggy line & duplicated layers please help ASAP

[kriz10]

Working on a powerpoint for a customer. Has to be finished by tonight uhg!

Everything was going great until i came back from lunch and opened my master slide design in xara pro 3.2. Now I have duplicate layers that wont turn off and can not be deleted as well as all my lines and vectors are all jaggy.

I am loading the file for you guys to see. Does anyone know what has happened or if it can be fixed? I would .. really really .. rather not start from scratch again since i have other charts and the second slide to create.

Thanks for any help.
