To get rid of the force close of the htc keyboard just change your input method. Htc is selected by default so switch to android keyboard. The same thing happened to me!well i finally was able to download astro. So i went into my download folder, and i deleted all of the htc_ime files that i saw in there. I was still getting some force closes, so im going to restart my phone now and see what happens. Im hoping this works because i really dont want to have to go through the whole unrooting and rerooting process. I will let you know shortly what happens.
I had the force close problem with the htc ime keyboard too one time. Just go to settings>language and keyboard and uncheck anything dealing with the htc ime keyboard so that the only thing checked is the android keyboard. That should fix it (at least it did for me).
