reinstall Voyager

Hi @ all,
I’ve some problems with the Voyager and in the first time with the Mozilla too. Both web browsers didn’t funktion. The Mozilla showed only the startup picture. After that nothing happends.The Voyager does the same and I couldn’t do any thing for 5 minutes.
So I had reinstall the mozilla (v0.7) and it starts without problems. After this I installed the Mozilla v1.0 and it works, too. So what can I do to run the voyager?
