Express Accounts 4.49 - everything has just disappeared

[liukchik]

I have been using Express Accounts 4.49 on a Mac 10.6.8 for three years with no problems. But, this evening I opened the program and my whole company profile, so all customer and invoice records, items, etc had vanished - it was a blank slate. I have checked Library/Application Support/NCH and everything was created at the point I opened the program tonight. So, before I manually recreate everything, is there anyway to retrieve this data?

 

Any help you can offer me would be gratefully received.
