sync server error and moblie device error. help

hi,
while im connecting my iphone to my computer, i receive 2 system error messages in itunes (im using itunes 10.1.1.4 on windows XP) :
1. syncserver error (SyncServer has encountered a problem and needs to close)
2. mobileDeviceHelper error
after this 2 errors there is another error from itunes:
"itunes was unable to load data class information from sync services. reconect or try later".

when im syncing any file to my iphone , i recive all the error again and again (maybe 10 error one after another) and after all i recive one new error:
itunes could not back up the iphone because the backup session failed.
despite all the errors, the files are sync to my iphone.
i tried to uninstalled, and to install older version of itunes but nothing help.
any idea or solutions?
thanks
