I tried to flash clockwork from rom manager and I keep getting an error. D1
Did you buy the rom manager or using the free app you may need to upgrade to the latest version. If its not that then do a fix permissions in rom manager reboot then try install clockwork again. Your not supose to flash it you install it. And you should have busybox installed as well. Z4root if it took should have installed that for you as well as superuser.
