v2.4.0 patch

Hi all,
There was a bug in the training routine in the initial 2.4.0 release. Since its so soon since the release, I've just replaced the 2.4.0 release with a patched version. If you downloaded in 2.4.0 in the last 10 days, you need to re-download it. Sorry about that and thanks to Paul LaForge for bringing the bug to my attention...Tom
