Gift Certificate lookup Fatal Error

After I upgraded to the latest AWO Coupon, when I look up a coupon, I get this:

Fatal error: Class 'AwoCouponModel' not found in /home/*********/public_html/****************/administrator/components/com_awocoupon/models/assets.php on line 11

I get this whether I lookup using the form, or if I scan the QR code on the gift certificate.

Hello,

Please upgrade to the latest AwoTracker, 2.0.1. The initial version is incompatible with AwoCoupon Pro 2.1.5 and up.

Thank you. Works fine now.
