Ticket from David Petkovsek - Certification Exam

I have signed up twice to test and both time the system would not allow me to start the test. Both times I got on with the tech support and they referred me to HUD where I get a voicemail. Can I either get some assistance with testing or find a local testing location? thanks - David Petkovsek, 386-627-3182, Dave@realtyexchangefl.com.
