Adobe Update Error

So I have the CS5.5 Master Collection and I'm trying to do updates for the following programs:

1. Adobe Extension Manager CS5.5 (This update adds integration with the Adobe Product Improvement Program.)
2. Adobe Flash Builder 4.5 (This update includes Flex support for Apple iOS and BlackBerry Tablet OS devices, as well as fixing important bugs.)
3. Adobe InDesign CS5.5 (7.5.1 Update. This update provides key fixes in the areas of Text and PDF export.)
4. Photoshop Camera Raw (Update to the Camera Raw plug-in that ships with Photoshop CS5.  Adds raw support for new camera models.)

And the error code I keep getting is as follows:

There was an error downloading this update. Please quit and try again later. Error Code: U43M1D204

Anybody know what this error is? I've tried downloading these updates 3 times now.

Thanks for any feedback,

Thomas
