[daip] Error in aips

[Itziar de Gregorio Monsalvo]

Hi,
I am Itziar, a summer student. Since friday I receive this message in AIPS:

ZMSGXP: EXPANSION FAILED ON FILE DA01:MSD1VK000.1VK;      NREC =      0
MSGWRT ERROR      2 AT XPND

I can run task, but the message appear between  every sentence.  Do you know 
how could I repair it?.

Thank you very much,

	Itziar
