Can't Sync or DL any playlists or Songs to my Ipod 4 8G

[Eublar]

So I have been a premium member for a little over a year and a half I do believe. I have never had a problem till about a mounth ago. When it happened It would not let me listen to any of my playlists besides all the songs on my Local Files that were already on my Ipod. ( BTW I use this for offline mode since its a must at my job since I work overnights =\ )Now I figured it was prob a problem with the update that i downloaded and would prob be fixed in a bit. Well I got a little impatient and went ahead and deleted Spotify from my Ipod then redownloaded it. Well now my Ipod will not even sync my local songs from my computer back to my Ipod it just says on my PC spotify pending. I don't think I'm the only one with this problem it seems just looking for some help. I have 4.44Gigs to use from what it says on Spotify so dont think that is the problem. I have relogged and everything mutlipule times. Also sometimes when I logout and back in over the works Your Music and even Playlists/Songs/Albums on the Ipod there will be a red line across it, not sure if that helps anything but its more info. If i come across anything elce or remember something I will post back. Thanks in advance
