DDDL 7.4 install Problem

[solarant]

I installed DDDL 6.45 and it boots up fine. I then installed 7.4 but when it tries to open I get a window saying

"an incident has been generated and stored in "c/Detroit Diesel/Drumroll/technical reports/incident report7.incident report"

Message: "Data interface: 05125: No valid license file found (004).
I should also add this a reinstall. The program worked but I had to uninstall it.
Then the program shuts down.


Anyone out there know what is happening.

I had the same problem found out I did not install the SP1 after I installed DDDL. I then installed SP1 drumroll error went away.
