Hi,
I too decided to go the Amazon Digital down load (UPlay) route, it was £4, a cheap experiment (and steam are good at reimbursing).
The install went fine and I applied the TWoS Mod and then TDW_GenericPatcher_v_1_0_168_0. All seems OK except for missing fonts. I've attached screenshots.
(I fear your thread may have been hijacked, let me know if it's an issue and I'll create my own thread.)
