Yesterday I created a report in Visual Studio 2008 with about 20 subreports, each subreport containing a single aggregate query (i.e count or sum). I then saved the report file. Hours later when I attempted to reopen the report in Visual Studio I recived the message box "Crystal Reports ActiveX Designer Failed to open document". The report file was completely unusable - it could not be opened for editting.
Today I repeated the process twice (once ith multiple subreports and once with all aggregate queries combined in a single subreport), only to have the new report files become unusable with the same error message. I am completely shocked at this behaviour from Crystal Reports. I have now spent 10+ hours with no usable report. I realy need a fix for this ASAP!!! Any suggestions would be greatlhy appreciated.
