Feel free to download the latest assemblies for the .NET Framework 1.1 and 2.0 (ajaxpro.2.dll) from my web site. The example project download still includes the old version, don't forget to replace it with the newer release.
If you have questions or any other feedback please use the Google group. Currently we have about 2050 members, still growing everyday. If you do a search for ajax you will find two great groups having more than 1000+ members.
