Thank you, Ludek. We called SAP and explained our problem again and was given the link to download the full build with SP 7 rather than the download page with all SP's and Fixes.
I uninstalled CR08, reinstalled using the new file. Crystal Reports closed with the attempt to link tables.
I followed DJ's instructions in changing the registry key. Crystal Reports closed again.
So here is a bit of additional information which may help.
I do not have a problem with Crystal Reports linking to a local (Access-based) Database. My problem is when I link to our accounting database hosted on a off-site server.
Any other suggestions?
