Whenever I try to connect to my generation 1 Zune 30 in the XNA Game Studio Device Center, I select my Zune and press next, only to recieve this error:

System.NullReferenceException: Object reference not set to an instance of an object.

What gives?

I am running Windows Vista Ultimate 32-bit with Visual Studio 2008 Professional and the Game Studio 3.0 CTP

Have you installed the new 2.5 firmware onto your Zune through the Zune Software?

Yes, everything is up to date. I'm utterly stumped.

Is your Zune currently syncing with the Zune Software? That will cause problems.

Have you tried restarting your computer? I know it isn't a requirement but it still might help.

The Zune is not syncing, and I have tried restarting multiple times, to no avail.

It really sounds to me like you have upgraded the Zune software, but you haven't upgraded the Zune firmware. Can you double-check that there is not a firmware update available for download when you look at your device through the software?

I have previously double- and triple-checked that both my software and device are version 2.5 prior to starting this thread.

I've flashed two first generation Zune's and a second generation with no issues so far. Wish I had some more suggestions for you. Hopefully one of the Microsoft developers pop in with some suggestions. I haven't seen any other threads with this error yet, but if I stumble across a solution I'll let you know.

Hmm. Well this is unfortunate. Thank you for all your help guys. If I figure it out I'll post the solution here for anyone else who may come across this problem in the future.

Up above you mentioned that you were having problems syncing? Does the Zune PC client work okay with your Zune? What is the build number running on your Zune?

 

Oh no I think you misunderstood. I meant the Zune was currently not syncing when I attempted to connect to it via Visual Studio 2008. The Zune software works perfectly with the Zune. But even so, version 2.5 (1614).

I am having the exact same problem.  At first I was able to connect it but the next day it wouldn't connect.  For some reason I unpluged it and started to listen to some music and came back to try again and it was able to connect and I was able to put games on it.  I then started to play the games I put on it and wanted to put more on so I connected it again and the problem happened again.  I would delete the device from the Device Center and try to put it back on and it would tell me it can't.  I don't have the software open and I have restarted my computer and zune multiple times.  I don't understand why I was able to do it once and come back later and not beable to do it.

I think I figured it out.  I think you have to have the wireless sync off.  I turned mine off and it worked again.
