Thanks to srtie4K I was able to recheck my Key# and I did write it down correctly.
, but definitely try to get help from Steam first since you bought it through them and try what srtie4K suggested.
Aka_STEVE_b Just be forewarned - UBISOFT support is horrible, ( not that steam is much better ) UBI practically asks for your 1st born child along wayy too much info to get any help from them.
