i can't seem to find this. TTLG isn't working anymore. i found 1.1.0 on WineHQ, but it tells me "the patch cannot be applied to this version of T3Main.exe", and i've also read there's a 1.1.2 version.

can anyone help me out?

EDIT: three years on GOG and only now do i realize i spelled my username wrong. curses!

yeah, TTLG is down for the moment. the mirrors should still work;
