I am getting this message when I attempt to run a report in my WinForms app:

The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception

I have spent the last week Googling & researching this. I have tried many different things, and I'm still getting it. It doesn't occur on
my development machine, only on my test box.

I know there's not much here to go on, but I'm really stuck and I have to deliver this soon.

Thanks
