downloaded the new wallet and the blokchain. After opening it tells me the database needs to be rebuild. The wallet will say 'wallet loading' and nothing else happens. I tried on 2 computers, one i left running overnight and now its still on the 'loading wallet message'. Closed the wallet. Tried again, now it showed someactivity (loading block index) and gets stuck on 'done loading' now everytime i start it will stay on this message and no more activity.
