MultiWii Pro Arduino compile problems

I’m a newbie to Arduino. I’m using Windows 7 64bit. I loaded Arduino through the Windows installer which appeared to have worked. I had downloaded the files recommended for controlling the above “MultiWi2_3-navi-b5-baro_fix.zip”.
When I try to compile I get error messages. Since I can find no reference to anyone else having had this problem I can only assume I’m doing something wrong.
I’m attaching a file showing the error messages.
Could anyone help me please?

It looks to me, like you have somehow included the header file for that library, twice.

That's what the error messages are telling you.
