MS Word crashes on opening document containing refs

Hi,

when I try to open a document containing references made with Endnote X2, the computer reacts with a message ‘request for viruscheck’. This leads to nothing but another message ‘program does not react’.

My anti virus program is AVG. My text editor is MS Word. The operation system: Vista. The problem also rises, when AVG is turned off!

The document was made on this computer, just a few days ago!

What should I do to get things working again?

Thanks! Jammer
