I have no 'desktop'! Only notifications work.

Ok, was going to reset my phone, but I had to put back some APKs and then unroot before. So here's what I did:

* Put all stock APKs on my sdcard
* Moved all APKs from sdcard to /system/app/
* Unrooted, restarted.

Now it's just a blank screen with a notification bar I can access. Task Manager is in there and everythings running fine. I was using LauncherPro at the time so I'm thinking it's trying to look for the program and not finding it.

What do I do?

Edit: Put LauncherPro apk in /system/app, looked over and it asked me to use Launcher or ADW. Chose Launcher. It rebooted, same black screen.

Edit 2: I said screw and did a hard-wipe. Worked.
