PS6 update error

I try to update PS6 from the Help/Updates menu and get the following error message:

Adobe Application Manager

There was an error downloading this update. Please quit and try again later. Error Code: U43M1D207

My version of PS6 is: 13.0.1x32

I am running WIndows 7 and IE9.

I have LR3 installed-I don't know if this is a problem.

Thanks for any help.
