I expect that this has already been covered by several people already but recently i have been working with the MSTS2Lomo converter and i have stumbled across the whole .dat files being too big for Lomo to handle.

I have trawled for information on how to do this properly but still have no idea as to what it is i am doing wrong. I have read that Illegal Alien had a guide for it but right now it is offline.
I will state what i am using for the botched conversions,

Vehicle Creator 0.07Alpha
Palette Express

btw the size of the DAT's i have been getting is around the 12 Mb mark, jes for some useless info. lol.
