newdev.exe Bad Image

I finally got my new iPad 2 (Wi-Fi) and haven't been able to get it to work. When I originally upgrade to iTunes 10.2, it told me there was some kind of communication error and I wouldn't be able to communicate with iPods or iPhones. I eventually uninstalled iTunes and reinstalled. I'm on Vista 64 bit, so downloaded that version.

Now when I plug in my iPad is tried to load the necessary drivers, but gives me a newdev.exe - Bad Image message. The rest of the test is:

c:\windows\system32\wpd_ci.dll is either not designed to run on Windows or it contains an error. Try installed in the program again using the original installation media or contact your system admin or the software vendor for support.

When I click OK, I get a Device installation error. A couple of times it's said it found new hardware and asked me to insert the CD that came with my iPad (which there isn't).

After waiting months to get this, I'd really like to get it up and running. Any advice? Thanks in advance...
