(It was ticketed on 20 May 08 for first departure on 1 April 2009, since moved to 30 April 2009.)
The first flight has to be within one year of ticket issue, and the ticket is valid for one year after the first flight. Since your new departure date is still within 1 year, there shouldn't be a problem. The coupons not valid after will probably only be changed in case of a reissue, so it looks like everything was done correctly.
