Hello LuciferOG,
I can't help you with the conversion issue, a direct message to mok through these boards or his website might get a faster response.
In game there is the option to upload and download maps that have been put together for this latest version of Empire. I have not looked at them for some time, but I believe all of the old scenario maps from ED, EDIE, etc. were there.
It is in the Build/Load A Map screen in the bottom left corner. Hope that helps.
Cheers :)
