Microsoft Plus! 4 Windows XP 1.00.00.0536 Question

[snackwell]

I have Microsoft Plus! for Windows XP Version 1.00.00.0536.

When I start it, it says there is an update to download, which I download, and attempt to install. The file is PlusServicePack01.exe (or some similar name) from the Microsoft site.

I did some research and this update is for 1.00.00.0554 to 1.00.01.0732. Was there an update for 1.00.00.0536 to 1.00.00.0554 that I missed?

If so, can someone forward me the file or post a link?

If not, any sugguestions?

Thanks!
