I keep getting error code: 13014

I have an ipod touch 2nd gen, my laptop is a sony vpcee25fx x64, I have used this laptop over and over and never had any issues, however about two weeks ago I purchased several songs and tried to sync them to my ipod, well I got an error code 13014, my ipod keeps repeating this error over and over as long as my ipod is connected to my laptop, I have removed itunes several times with no luck, I have done a hard start on my ipod several times a day but nothing seems to work. I purchased a new cable, my battery is fine, i just can't sync, oh yea for some reason the few times I'm allowed to get most of my songs back my ipod storage bar shows i have no more storage, I know my ipod holds over 9800 plug songs because that's what was on my ipod before all these errors started. any help is appreciated.
