We have just released an update (v. 2.0.5.120) that should fix this issue for you! Please check the market in a couple of hours by which time the update should be available
Sarah Reynolds
Frontline Support Lead, SwiftKey
The update (Version 2.0.5.120) is now available on the Market AND NOW on Amazon. If you got this on Amazon before yesterday, be very careful that you don't 'upgrade' to the older, white version. If you got the new, black SwiftKey X for free on Amazon yesterday, Amazon may not yet say that you have an upgrade available but if you uninstall and re-install SwiftKey X you will get Version 2.0.5.120 which works with the HTC email app on the ThunderBolt.
Way to go, Sarah & James!
Thanks, Robrecht
