I am having the same problem and everything was working fine. I too updated
to Beta2--obviously a mistake.

Hello all,
Up until a couple of hours ago- everything worked great- using the beta 2007
ms office. I just updated the beta version with the Beta2 teachnical
refresh- & I can't open any excel files or word files- not one! the error
says that there is a conflict with my anti -virus program & that the file is
corrupted, so I disabled the anti-virus program& tried to open them again-
same problem- every single file effected. Has anyone else encountered this
problem? Any solutions?
