Hi Mephisto. Thanks for posting your reply.
Here are some answers:
1) Emp is created for 5000 point empire. If you have selected a 2000 or 3000 point race bonus, then it produces error. I will post separate 2000 and 3000 emp files for Sergetti later this day.
2) I have noticed this bug just after I uploaded these files. I have updated them with the correct one, so there is no error message any more.
Thanks again for reply. I hope to hear more from you.
