Old Version Message Box

I downloaded the Outlook plugin and installed it just now.

The system keeps telling me that I have an old version and that I need to download the new version. But every time I download it again, it's the same message.

I tried clearing my cache and cookies, I tried downloading it in IE7 and Firefox. I also tried downloading it on multiple computers and keep getting the same message.

When I click properties on the download, it says it's version 2.11.15.0 - is that the latest one?

This problem could easily be fixed if you guys would append the name of each upgrade and add the version number in the file to distinguish it from the previous version. It's a simple fix and would save a lot of headaches.

Thanks.
