Crashes and cant link my card

When I first installed it, I was able to search through some things but when I tried to link my CC for the ewallet, it said I had to verify my email... But I never got a confirmation email to verify it (and I tried to resend twice with no luck). Now whenever I try to launch the app, it crashes. Please fix.
