Is Atelier's "Check for Updates" broken?

Hi John,

We fixed an issue this morning. Could you try that again and let me know if that works now?

Thanks,

Joyce

After update  today Atelier crashes when opening the old workspace.

With the new workspace Atelier explorer has an error

Plug-in "com.intersys.eclipse.ui" was unable to instantiate class "com.intersys.eclipse.ui.views.AtelierExplorer".

And Server explorer does not save connection even when it test it ok.
