Windows 7: Itunes Iphone Lose Sync

Windows 7 Ultimate 64Bit
Itunes Iphone Lose Sync

I have just upgraded to windows 7 ultimate 64.

I though Brilliant as it i can have itunes on it and it will work with my iphone sync.

Ok it sort of does apps work fiune abut when i want to transfer movies and music it doesnt work.

Before I start i do not sync my musi, i choose what goes on as I have more than 8gb of music.

The first way I tried was simply selecting the songs and dragging them on to the iphone. It seems to work out fine but then it says that The iphone has lost sync and stops copying.

I then tried

Creating a single playlist with what i want on my iphone and making sure the iphone nly uploaded that playlist. Same thing happens, it loses sync.

It only uploads about 4% of the music which is 3.4gb worth,( I have 6gbs free on my iphone)


When these rrors occur my CPU usage goes up to 100% and it means my computer is un bearably slow and its a struggle to shut it down.

This happens everytime, anyone got any ideas what the problem is?

p.s. its an Iphone 3g
