Expression Host Files being created

VB2005, using Report Viewer in local mode.
My program worked on all the PCs in the office. However, a new PC arrived last week, and reports won't generate on that pc.
 I get a message about
'C:\Documents and Settings\theusername\Local Settings\Temp\expression_host_abc12324334435435435 in use by another process'

In the temp folder, an expression host file seems to be generated just before the report is supposed to open. On all the other PCs, there are no expression_host files. Why are these files there?
I've tried other programs that use report viewer, and none will work on this pc.
Any ideas on how to fix it?
