Are you running the keytool -genkey - alias wwa -keyalg RSA -validity 20000 -keystore wwa everytime you sign?
If so, you should only generate the key once and use the wwa key to sign all versions of your app. Also, in Settings -> Applications make sure Unkown Sources is checked. Finally, you can try uninstalling the app first then re-installing it. This is a simple answer, and may not solve your problem.
