Every ROM/theme i've used takes black market, it's just a matter of if the system auto updated to the new one, that's whats causing all of the problems.
Im fighting with my droid X trying to install your file again. It goes right on my d1 with your update.zip fine, but with my x I have to use root explorer, and I usually just make sure I get the update working named just as yours is then I drop it onto the other file overwriting it in data/app. I then make sure permissions are set 6.4.4. Now I go to application/manage apps/ then I select all and scroll down to maket. I then delete data.
Now I click home and hop out of root explorer and open market. This in the past has worked with all your versions once I figured that method out. This one its not working so far. I'll keep messing with it to get it going cause I cant stand this green/white market yuk.
