I get the error when trying to run the Online version at "this page" (http://www.sweethome3d.com/SweetHome3DOnline.jsp). I have not attempted to install or use a download version. Thanks.

When trying to start the online version, I get the following error: ClassNotFoundException com.eteks.sweethome3d.applet.SweetHome3DApplet.

Don't see this in the FAQ or another thread. Runing IE9 with Java 10.7.2. Thanks for any help.
