Probleme to export .rad

Hello !

When I want to export my .rad document, Hypermesh displays :

'error 0

while executing
'*cardcreate HEADER_CARD'
    invoked from within
'if {$FE_type == 'RADIOSS' && ($FE_subtype == 'Block51' || $FE_subtype == 'Block90' || $FE_subtype == 'Block100' || $FE_subtype == 'Block110' || $FE_su...'
    (procedure '::Export_GUI::FE_Accept' line 1)
    invoked from within
'::Export_GUI::FE_Accept $toHC'
    (procedure '::Export_GUI::Accept' line 12)
    invoked from within
'::Export_GUI::Accept'
    ('eval' body line 1)
    invoked from within
'# Compiled -- no source code available
error 'called a copy of a compiled script''
    (procedure '::hwt::ReleaseCanvasButton' line 1)
    invoked from within
'::hwt::ReleaseCanvasButton 0 .g_Export_Tab.buttonsFrame.applyb'
    (command bound to event)'

It does'nt export my document and this the case for all my .hm documents.

Do you know why and what can i do ?

thank you !
