Canada Post Shipping Module not working all of a sudden

[netwerx]

We have been using OsCommerce for 2 years with the Canada Post shipping module. For about the last 3-4 days, we have this error come up during checkout at the shipping stage:

"Cannot reach Canada Post Server. You may refresh this page (Press F5 on your keyboard) to try again. If you prefer to use canadapost as your shipping method, please contact the Green For Life via Email."

All set up info in the admin area is as it always was... anyone have any suggestions on where to start looking for the solution?
