InfoPath Dev

morning.

i'm not able to open my form with infopath 2010.
when i try to open form, infopath tell me:

Impossibile eseguire la query per l'oggetto DataObject seguente: anagrafica_sale_cinema
Impossibile aprire s:\Cinema\_VR_IN\anagrafica_sale_cinema.xml: le connessioni a file XML in percorsi locali sono consentite solo in modelli di modulo completamente attendibili.

all form opens correctly with infopath 2007.
suggestion ?

inside Internet Options I have already activated the Access data sources at domain level.

The error message indicates that local data sources are only allowed in full trust forms, have you tried publishing the template as full trust to see if that fixes the issue in InfoPath 2010?  Perhaps some security changes in InfoPath 2010 is why this is happening and InfoPath 2007 didn't have those issues?
