When I try and set the data source to MS SQL via the Data Explorer, the MS SQL entry does not appear under the More Data Sources as I have seen in the past.

When I preview a report previously setup with a MS SQL data source, I get the error
The library "" cannot be found. Please check your installation. and then, Cannot open database, and then Physical database not found.

I am running XP Pro SP3, and have Visual Studio 2003 installed (after the Crystal 8 was installed originally). I have MS SQL 2005 Express installed.

I have tried re-installing Crystal, ensuring the MS SQL data access is ticked to install.

I have checked that I have both P2lsql.dll and P2ssql.dll in the Windows\Crystal folder.

Please advise.
