expired coupon

Hello,

I tried the plugin last year and it worked well, I prepared to reinstall my new site and there all the coupons that I created that is either directly or through the link shortcode was the message as the voucher expired yet I put away a date (30 June 2014), I looked beautiful and I have not found out why I have that, I’m looking if I filled out the parameters coupons and I tried on three different sites and I have the same thing.

Thank you in advance.
