btasm et.al for DBW, way I did it is drop the _Leo 451 INTO #DBW then download the attachment at very bottom of download page for 410_b2.7z users.(---I used the one that was downloaded 462 times) If you look at very bottom of _Leo451 there is FAE5FEA0B49E5C12 and LEO451FM. I deleted both those files. Now, back to the For_410_Users clip attachment d/l, Iopened the file and found FAE5FEA0B49E5C12 and LEO451FM. I copy and pasted those files to replace the original files and it worked. Of course, I had to do all the other routine stuff like the .ini file copy n paste etc.
>>>I know it seems like they must be the same files, but apparently they're not. Only Ranwers can can answer this I think. But I am somewhat illiterate in this kind of computer work, the whys are for greater minds. All I know is that this worked for me. Good luck.
Hope this helps somebody to get this beautiful bird flying
