iOS7 - iPhone 4S - Sync session failed to start.

When attempting to sync my iPhone 4S it after immediately plugging it into my laptop before and after starting iTunes, "iPhone could not sync because the sync session failed to start."

I'm running Windows 7 on my laptop using Safari and running iOS7

Last time i sync'd was about 4 days a go with no problem.

So far I have;

Open itunes--> Edit--> Preferences--> Devices

Delete the backup

Reset sync history

Close itunes

Open itunes, then File--> Sync

Still no luck, any suggestions????

Thanks!
