I've had the same website problem, my application was missing so had I re-applied....it is worth mention that while filing the application again most of my previous information (contact info, medical, etc) was in there...all I had to update was the flight experience and upload my resume along with a cover letter that was not requested on the old format....my status obviously changed and from Shortlisted I am now as "Application Received"
Good luck to all...
