I got the same error opening the file in Adobe Reader. I opened though in Preview (Mac PDF reader) and it opened fine. I then saved a copy in Preview, and the copy I created opens fine in Adobe Reader (my default PDF viewer). This is strange, usually Preview doesn't display my Catalyst PDF files properly and Adobe Reader does!
My suggestion to BattleCorps/Catalyst/Battletech,etc: Always test your PDF files in both Mac Preview and Adobe Reader before releasing them, to ensure that all your paying customers can view them. Saves us the work of fixing the files ourselves. :)
