Coupon Printer site won't print coupons???

I've been trying to print coupons for Listerine. I have Coupon Printer loaded on my computer. When I try to print the coupon, I receive a message:

"Sorry! You have already printed this coupon the number of times allowed."

I have never printed this coupon before. I'm getting the same message on a number of other products using Coupon Printer.

Any suggestions?????
