How to send Attachments to a pc!

Here is my issue, and ive wasted a good 30 mins trying to research it enough to figure it out. Im a new macbook user and have been using my macbook for the majority of my work related duties. Today i input my info into my timecard doc (.pages) and went to sent it to my payroll guy and to myself to make sure it went through. when i recieved it the single file was sent as a zip, when you open the zip on the pc you cannot find the actual document anywhere. WTH?! haha please tell me how to make this work. i already have send windows friendly attachments selected, view as icon and all that. i also downloaded attachment tamer but im not sure that is my solution, or quite frankly how to use it.

Thanks so much
