Problems with shipping modules in oscmax

[Posh Princess]

Hi I'm new to this forum and fairly new to oscmax. I am having problems with my shipping modules. I have a canada post shipping module but I am not sure where to install it (im not sure of the file structure it's different from oscommerce). I am also having trouble with the UPS shipping module It's not calculating the correct prices, and lastly the free shipping module is not working at all. If anyone can help me out that would be great.

Thanks on advance.

Can you provide a link to your site.

Make sure on your product the weight is set if you dont have the weight put something like 10lbs.
