migration from zen cart problem

[furnic]

I am trying to migrate from zen cart  v1.3.9d and it connects ok to the database but I get this error:
Warning: Chosen source cart is empty!

So what am I doing wrong?

thanks

Strange. Do you see any error in the log right after you try this? System -> Logs -> error log

Hi, no error log is empty.

I get this message:

Warning: Chosen source cart is empty!
