MarketPress for Canadian site: no "View API Signature"

Hi, (is Patrick around?)

I am in Canada, and want to use my Paypal account using USD currencies. Account Type: Premier
Status: Verified

I get a 10002 Error when trying to checkout on my store.

http://streamweavers.net/store/shopping-cart/checkout/

There was a problem connecting to PayPal to setup your purchase. Please try again.
10002 - Security error - Security header is not valid

Doing a search, I found that it may have something to do with the way my API is setup. Following instructions,
however, I cannot find a "View API Signature" in my Paypal account.

In My Account/Profile/Selling Tools/API access/UPDATE.

I only see two options:
- Option 1- Grant API permission
- and Option 2- View API Certificate

What am I missing? Someone from the UK can see "View API Signature" under Option 2, but not here.

HELP!

Regards,

Andre
