Can't read queries in Access 2003

I am running Access 2003 SP3. I am new to the company and am trying to fix a
problem on a file that was created by the last guy here. The one person who
uses the db had no problems until she migrated to a new laptop. Now she
cannot run any of the queries. It does not appear to have any security
enabled - no specific users or groups other than the standard Admin and User.
All objects had shown a db owner of <unknown>. I was able to make all other
objects belong to Admin except for queries. I also attempted to create a new
blank db and import every object into it, but I can't get queries as I can't
read them. They all show up normally under the query group window, but any
attempt to run them results in the error message "Could not read definitions;
no read definitions permission for table or query X." I also attempted to
remove the old system.mdw file and create a new one, which didn't work. The
user indicates she is not aware of any specific workgroup and had not been
required to enter a user id/password before.

Thanks in advance for all your help!
