I have a problem with error numbers 1881 and 2005
NOTE: I'm using Spanish version and I don't know how exactly the translation is.

In some occasions I have the error 2005
"Error al cargar el archivo - número de registro 21"
Translation: Error charging file - register number 21

However this is the error description of 1881 error

I don't know what this error means and how can fix it

TIA
