Can't Detect Updates For Office 2010 (Professional Plus Edition 32bit)?

32bit. I installed all of the software which I run on it without any problems.When I try to update Microsoft Office 2010 Professional Plus (32bit) Windows Update only finds a few updates, and after they're installed it doesn't find anymore updates. It doesn't even find Office 2010 SP1.{Note: I had no problems with other updates like Microsoft Visual Studio 2010 or other Microsoft updates.I tried uninstalling Office 2010 and installing it again but nothing changed. The privacy settings which show up the first time you run an Office application I set it as "Recommended settings".I also tried downloading Office 2010 SP1 (32bit) and when I tried to run it an error came up saying something like version mismatch (I presume that you need to install other updates before running the setup & I also tried to download an other update but the same error came up.)I didn't have this problem before I formatted the computer.}
