Windows 2008 R2 activation

Hello,

I'm trying to activate Windows 2008 R2 Standard on my computer and I get an error. I want to do the phone activation, but I do not get the phone numbers list (only a link to the help file), and I do not get the phone activation screen (with the fields for manual input). I looked for a number on the web but found only the volume license activation numbers. I have a standard license.

I live in Canada...does anybody know the number and how to get the phone activation screen?

Thanks.
