HELP! File not found

[kevlord]

I bought SEIV gold and patched it up to 1.78. I had loaded a bunch of mods from the CD and the web and was happily working on some of my own when I started getting "File Not Found" right after I ended the first turn. At first I stripped out all the mods and still got the message The unmodded game ran fine but the moment I tried running from a mod folder I got the error message. I deleted and reinstalled the game and still got the message. I copied the unmodded files to a separate folder and tried running from that folder and I still get the message. Can any one tell me what is going on? What file is it looking for?
