Where Can I get FCE4.0.1 Update

Hello All

Hope you can help.

I've recently had to wipe my computer and reload all the software back on.

However after loading the disc of FCE4.0 I can't find a update for FCE4.0.1.

I've tried the App store and several websites to no avail!

I use a Sony HDR-SR10 camera which records in AVCHD format, I can't use the camera data without the Update.

Can anyone help with where I can get this update

Many thanks in advance
