Deleting a Strategic Assets folder sounds like something awful. I haven't seen such a folder, myself; did you by chance mean GameAssets? If you deleted that folder, then that was the cause of your crashing. My mod does not ADD that folder and its contents, in their entirety, to your mod directory. It adds files WITHIN that folder, and another folder (Archives).
So, once you are done downloading, take the 1.2 copy, put it into your open DOW2 folder, extract, delete NOTHING, then launch, without changing anything else. Start a new game, you should be set. If something goes wrong, you did something again (like deleting your entire GameAssets folder).
