"iPod Setup Assistant " request always pops up upon mounting mono 20gb ipod

Question

Just installed 30gb ipod & itunes update onto computer running Windows XP - no problems. I also have a 20gb mono on the same computer (updated itunes and ipod updater as well). Restarted computer. I signed on as the only one using the PC, launch itunes, mount the 20gb ipod. The system does nothing for about 20 secs. then the ipod is shown (as it always does). No problem adding songs to libary or transfering to ipod w/20 gb (except the inital delay). The problem is, behind the itune window a window pops up "iPod set up assistant" with the name of the ipod I just mounted. Window ask me if I want to auto sync my files (I click off the check mark - because I do not keep music on computer otherwise this would wipe my ipod clean). I cancel out, but each time I mount the ipod I get the same pop up "set up request". Any ideas what is going on and how to stop this (so that I some day do not make the mistake of hitting OK in place of cancel)?
I have read the posting below but it falls short of answering my question.
Thank you in advance.

Answer:
First things first, lets get your iPod up and running with the correct firmware:
Begin by throwing away the disc that came with your iPod. The software on it is more than likely out of date anyway!
Download the latest iPod firmware from HERE and install it on your computer (by double-clicking the installer icon).
Go to Start > All Programs > iPod > iPod Updater > etc and run the updater application.
When the pop-up box appears, connect your iPod and select the RESTORE option.
When instructed, disconnect the iPod from the PC and connect it to the AC adapter to complete the process.
OK, now you need to decide 'how' you want to manage your music. You have a couple of options:
Using the existing iTunes installation on your PC
If you want to use the same library and iTunes installation, then you can just re-connect the iPod to the computer via the USB or Firewire. iTunes will launch and ask you to register the iPod. To manage your music, you now have two further options. You could either:
Use 'Auto-Synch' to transfer the entire music library and playlist selections to your iPod.
OR
Use the 'Manual Synch' option to manually drag and drop the songs and playlists that you want on to your iPod.
OR
Set up a 'Master' playlist which contains all the songs you like, and then set the iPod to automatically synch to that.
Using a new iTunes installation (Requires windows XP)
If you want to keep your new iPod music completely seperate from the original iTunes library, then you can install another instance of iTunes. To do this, you must:
Create your own XP user profile.
iTunes should be accessible using this log-in. If not, then download and install the latest version of iTunes. This can be obtained HERE. (Note: When swapping between User IDs, you should not use the 'Switch User' option. iTunes really doesn't like that!)
Once the iTunes install has completed, you can begin adding your own music. Your music files will be automatically added the the newly created iTunes folder which can be found at C:\Documents and Settings\[User Name]\My Documents\My Music\iTunes\iTunes Music.
If you want to keep all the music on the hard-drive in the same place (and minimise the possibility of having multiple versions of the same song everywhere), then you can change the settings in iTunes so that all music is derived from the same location. To do this, go to Edit > Preferences and select the 'Advanced' tab. You can then change the iTunes Music folder location to something like C:\Documents and Settings\All Users\Shared Documents\Shared Music.

Answer 1

To all of those who viewed question but did not have an answer the following is how I resolved my issue. FYI. In the end, although the "Setup..." window came up, it was in fact stating that I did not have the music file within my iTunes. How I resolved the issue was to first click OFF the check mark that advised me that iTunes would automatically update my songs. I did not change the name of my iPod (since it was the correct name). Clicked next and then Finish. This resulted in the window going away and the "Music Store" file appearing within iTunes. The "Setup..." box does not come back up.
