CR8 File not Found

Hi folks,

I've created a report with Crystal Reports 8 through VB via ADO, and send it a recordset at runtime to populate the report. This all works fine and dandy.

However I created another report the same way and inserted it into the first report as a sub-report (Both reports are saved in the same directory and work fine independently). Once this subreport has been inserted, if I try and run the main report, it pops up with "File not Found".

Anyone got any ideas what is going on?

Thanks

J
