I found this problem by noticing that the acronym package acro was inserting a blank page before the acronym list. I then discovered that not only was it inserting this blank page, but that list of acronyms weren't spanning multiple pages as they should. See image below:

I've created a minimum working example which gives me the blank page and also creates the acronym list error. (Note: If you comment out the acronyms used in the text body one by one, eventually you will reduce the list size such that it fits on one page and the blank page disappears.)

FYI, I'm using TexNicCenter but have also tested this with LEd and get same problem
