Hi,
I have a problem too, my computer was broken and I have to run EJS with the new SO windows 7 64 bits.
I can open EJS without problem, but when I open some file, the program give me a problem, this text:

Archivo leído correctamente: ops final_movimiento_entre_dos_puntos.ejs
Archivo grabado correctamente : ops final_movimiento_entre_dos_puntos.ejs
Generando el archivo de la simulación ops final_movimiento_entre_dos_puntos...
C:\HD Almacenar\programa EJS\EJS_4.3.7\workspace\output\ops_final_movimiento_entre_dos_puntos_pkg\ops_final_movimiento_entre_dos_puntos.java:22: cannot access java.lang.Object
bad class file: java\lang\Object.class(java\lang:Object.class)
class file has wrong version 52.0, should be 50.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
public class ops_final_movimiento_entre_dos_puntos extends org.colos.ejs.library.Model {
       ^
¡La compilación generó un error!

Can anybody help me please?

Thanks.
