No such element

[ghost]

If I run the script, it says:

Error:No such element
Check number of files in source folder

if I have a blank file opened before, though, the error message changes to this one:
Error 8800: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.

• The parameters for command "Save" are not currently valid.
  Line:240
  executeAction( idsave, desc3, DialogMOdes.NO );

The same here but on line 190.

executeAction( idCnvM, desc6, DialogModes.NO );

Hey @holyst4r in which language do you have Photoshop?
