Canada Post module

[carley]

I installed the updated "canadapost.php"

I put a fake item in my store to test it, that should fit well within the lettermail limits (my store hasn't "launched" yet, so it's all "test items" right now), but I don't have Lettermail showing up when I click on "estimate shipping". I also didn't have ti showing up before installing the updated php file.
I seem to only get results for regular shipping, not lettermail.

Any idea what i might need to change/fix here - any help or tips would be greatly appreciated?

Edit:
Also - i have enabled lettermail rates in my shipping module - it's set to "true", incase that info helps at all
