InDesign CS4 fails to open PageMaker 6.5 files correctly

Question

After upgrading to InDesign CS4 this week, I attempted to open a PageMaker 6.5 file. It opened, but the pages were out of sequence. PageMaker 6.5 pages 1, 2, 3, 4, 5, etc., opened in InDesign CS4 as pages 1, 3, 2, 5, 4, etc.
I purchased InDesign CS4 last week for the sole purpose of working on two books I created in PageMaker 6.5. For me, at present InDesign CS4 is useless. I hope Adobe provides a fix soon.
Also the upgrade rejected my PageMaker 6.5 serial number, I tried all the fixes at the Adobe website, finally after half an hour on the phone I was given a challenge/response code which then launched InDesign. If I need to reinstall InDesign, I'll have to go through the challenge response process again, i.e. another long wait on the support line.
I'm using OS 10.5.5 on the newest, unibody PowerBook Pro.

From the help files:
Flow text semi-automatically
With a loaded text icon, Alt-click (Windows) or Option-click (Mac OS) a page or frame.
The text flows one column at a time, as in manual flow, but the loaded text icon automatically reloads after each column is placed.
Flow text automatically
With the loaded text icon displayed, hold down Shift as you do one of the following:
Click the loaded text icon in a column to create a frame the width of that column. InDesign creates new text frames and new document pages until all text is added to the document.
Click inside a text frame that is based on a master text frame. The text autoflows into the document page frame and generates new pages as needed, using the master frames attributes. (See About masters, stacking order, and layers.)
Flow text automatically without adding pages
With a loaded text icon, hold down Shift+Alt (Windows) or Shift+Option (Mac OS).
