PDF not opening from a link

Hello! I'm trying to renew my permanent resident card.  On Immigration Canada's website, I have clicked on their link to open up the application form. A PDF page opens up which states "Please wait. If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document." It then tells you how to upgrade to the latest version of Adobe Reader. I have downloaded the latest version, but it makes no difference. I still can't get to the application form. Being Immigration Canada, there's no way of communicating with them. Does anyone have any thoughts on what else might be wrong, or if there is other action I may be able to take? Thanks very much.
