Fails to launch - even after reinstalls

Installed to my first gen MacBook Air. Installs properly, or so it says, but crashes consistently on launch. Reading other reviews see the issues with storing identities in some other cloud service, so even if they fix it, I wont bother trying it again. Pretty is no excuse for lousy security, not that I could even see pretty since it wouldnt launch at all.
