All credit goes to Terry (tlsjr117) for figuring this out. This is a direct copy paste of his instructions from the OFL forums.
The terrible thing about this is that the people at Cyanide were either too stupid or too lazy to mention that there was a way to patch your Steam version manually so you could actually play the game you paid for.Ok The update patch defaults its output to the file locations that Cynide has set up for blood bowl
location some thing like this
C:\Program Files\Cyanide\Blood Bowl Legendary Edition
But Steam creates another copy of the file here
"C:\Program Files\Steam\steamapps\common\blood bowl legendary edition
the trick is to run the update. this will create the folder and files in the first path above. once the patch is complete just browse out to the location copy all the file ( no folders just files) and then browse to the steam location for the game copy the files in.
when propted just replace any files with the new ones.
Waaa LAA good to go.
I'd suggest backing up your Legendary Edition folder just in case something weird happens when Steam releases their patch, but Terry and I both used this fix on our versions last night with no problem.
