Close your file in FM Go before hand. In FM Go, select "Windows" (from windows menu top left) and the "Close all windows" (from settings menu top right.) This forces FM Go to open the new version the next time you select it from the Recent Files or Files on device menus.
Alternatively, you can double click the Home button and slide the FM Go window upwards to close the app. The next time you open FM Go, your new version should show up.
Thank you for your post.
In addition to what "Jade" says, make sure your iPad is not locked, as the passcode security feature in iOS 7 will not allow copying of files onto the iPad.
You can also use Drop Box to wirelessly copy FileMaker files back and forth between computer and iOS device.
