I need to download the latest service release for NetAdvantage for .NET 2008 CLR 3.5, to resolve a problem around ASP Webgrids which has been confirmed as fixed.

I currently have Vol. 2 (possibly with no Service Pack) installed (8.2.20082.1000) and when I try to install the latest Service Release for Web Client (which I presume is a new name?)  it tells me I don't have the product installed?

Am I downloading the correct service release, and if not, where should I be getting it from?

TIA
