IPod Touch 4G won't sync new apps on 2nd authorized computer, but WILL sync music, podcasts, etc.

Question

Hello.
Everywhere I've read about apps not syncing to the iPod touch while using iTunes on a second authorized computer have mentioned that they could sync nothing to the device. Yet I have a different problem, one where I have no problem syncing new music, podcasts, pictures, etc., and only new apps refuse to sync to the device.
I recently purchased a new iPod Touch 4G. My computer being away for repairs at the time that I bought it, I synced only podcasts, apps, pictures, and video to the device using a friend's computer under a different Apple ID. When I first synced it, I authorized that computer with the device, and it mentioned you could sync the device with up to 5 computers, so I figured I would have no problem when I got my own computer back.
Having now received my computer back, I connected my new iPod touch to my own iTunes under my Apple ID and authorized my computer as the second authorized computer. These are the only two computers I have ever synced the device with.
I copied my music library, more pictures, and more podcasts to the device with no problems, and they play/show on the device no problem. Also, I can still access and use all the content previously on my iPod.
I have downloaded a few new free apps that I wanted to sync to my iPod using my computer, but when I go to sync them to my iPod, they won't sync to the device. I have downloaded all the apps I had originally put on my iPod using my friends computer so that I would receive updates for the apps automatically. I have not tried to sync these, though I have (or iTunes at least is telling me I have) synced any updates that have since come up for the apps already on my iPod.
I have tried clicking and dragging the new apps from the apps tab over to the device tab, and iTunes shows them syncing, and to the best of my knowledge, shows that it has finished syncing them. It also shows that it has completely synced all the new apps when I try syncing on the apps tab under the device tab (the one that shows up when you click on the tab for your iPod, and is next to Summary, Pictures, Video, etc.). I have all the boxes checked off, and the boxes next to all the apps are checked off as if they're on my iPod, but they don't show up on the screen display next to it. When I click and drag the new apps over so they appear and click "apply," iTunes shows that it has completed the syncing process, but the apps won't show up on my iPod, and disappear from the sceen display on the device apps tab the next time I sync my iPod.
I have the latest version of iTunes, and have downloaded all updates for it. My iPod's less than a month old, so I don't think there's any updates for the iPod itself.
I also currently don't have the ability to sync over wi-fi, or have wi-fi access on my iPod at home, though I could set it up if it would fix the problem. Right now, I'm only syncing my iPod using usb and iTunes.
I would prefer, if possible, not to have to restore the iPod to factory settings, and begin anew. However, if this is necessary, any help on how to restore the iPod and back it up would be much appreciated.
Any help you can give is awesome.
Thank you for your time.

Hey, I'm probably too late and you may have already solved it but here's a solution. In iTunes go to Edit then preferences and then click on reset dialog warnings. What happens is when you first sync your ipod, you receive a message saying something like transfer?and you've probably selected "Do not show this message again". I don't really know why but iTunes assumes that the apps on your iPod are already on your computer and therefore need no transferring.
After you've reset it, the same message should pop up about transferring. As long as you don't click don't show, you should be good to go.
