WTH? Problems with iOS 8 compatibility

I made a rookie mistake by not checking on the effect an update to iOS 8 might have on this program. I have it installed in my MacBook Pro, iPhone and iPad. Because I haven’t made any changes on my Pro, I still have access to all of my information. I cannot open nor access anything in my other devices. When I tap the icon on the iPad the screen goes black for a millisecond then goes back to the home screen. My iPhone opens the sign-in window, and after entering my password it also flashes back to the home screen. So WTH mSecure? Do I need to delete the program and download it again? If I have to do that and pay for it again, that irritates me! Your software engineers should have been in front of this a long time ago!
