I am using crystal 8, enterprise 8.5, and I am unable to export into excel via eportfolio.

my users use NT machines, and when they try to exprot a screen quickly pops up and then dissappears. On an XP machine I get the following error messages, and then it opens up.

Error message:
<filename> could not be found. Check the spelling of the file name, nad verify that the file loation is correct. If you are trying to open the file from your list of most recently used files onthe file menu, make sure that the file has not been renamed, moved or deleted.

Detailed below are the fix details from the XP machine

The following is a list of repairs:

Renamed invalid sheet name.

Any ideas on how to get this to export correctly on an NT machine, and how to remove the errors from the xp export?

Thanks for all your anticipated help
