Enhanced Paypal Shortcodes v0.4 not working w/WPv3.0.4

I have been using Enhanced Paypal Shortcodes for sometime now. However, it isn’t working with WP v3.0.4. I deactivated ALL plugins except Enhanced Paypal Shortcodes and it still didn’t work. The website in question is http://www.4sharpscissors.com and the short code is there, just above the related text, even though it doesn’t display the Buy Now button.

The shortcode is as follows:
[paypal type=”paynow” amount=”97.00″ email=”arterinc@hotmail.com” itemno=”4SS-100″ name=”4SS-100 Scissors Sharpener” noshipping=”2″ no_note=”0″ currency_code=”USD” imageurl=”https://www.paypal.com/en_US/i/btn/btn_paynowCC_LG.gif” returnurl=”http://www.4sharpscissors.com” imagewidth=”150px” textalign=”center”]
