I looked into all my folders and that file doesn't exist anywhere, I found it in my unpacked MTW2 on my other HD and copied it over and the game loaded a little further but then came up with an 10:07:26.984 [data.invalid] [error] DATABASE_TABLE error found : error reading record from file mods/PDER_1.0/data/export_descr_unit.txt. I'm reinstalling PDER now on a fresh game. I didn't even do any editing. lol It's really odd. With reinstall I can see the ProdeoetRege screen then it comes up with an error. I think MTW@ is doing a trace and is loading up the regular MTW files.

I have to go to work now. Will try to figure it out later, but this is coming from a clean install. without unpacked data files. I have no clue what's going on with it either.
