Same here
I had to uninstall/re-install at least 4 times before ending this bug and I still don't know what occurred this bug ( except a patch problem itself )
Of course, I patched upon an original TS3W.exe and TSLHost.dll ... and without any .packages and any NRaas mods I usually use.
Now, I have a new problem : the game crashes A LOT and always the same error : "Unhanded page fault on write access to 0xcdd281b0 (example) at address 0x00e09503 (example). Do you wish to debug it ?"
Still searching and trying some experiments
