Strange? It could be that you tried to restart the server too many times in error and it caused the problem. It all seems ok now anyway.
One thing we have noticed is that you have files of all varying different bitrates. It is important that all the files for your AutoDJ are at the same bitrate as configured for your server (128kbps). Not only can this cause playback issues with certain players (such as flash), but it is also eating up your storage capacity as you have a lot of files at 320kbps and 256kbps.
In regards to the crossfading on the AutoDJ. We decided to disable this feature as it can be quite taxing on the servers if all of our users were making use of it. Also, depending on the style of music played and if it has a drum beat on the intro or outro of a track, it can sometimes sound a bit rubbish in our opinion when the overlaying tracks clash. We just need to remove the feature from the control panel settings to prevent any future confusion.
With the request form, are you using the widget code as supplied in your control panel under the 'Configuration' / 'Widgets' section? We can see that you have this enabled in your settings, so as long as your email address is valid and you use the widget code snippets for your website, this should work with no problems.
