Missing DLL

Are you sure about the name??

google TBAUBIOR.DLL find out exactly what it is.
look on the game cd see if its there somewhere.
it may be in a .cab or.zip file in which case use 7zip to extract it.
use google again to find out where the .dll goes weather it be somewhere in the game /dir or system /dir
such as : c:\program files\game name\data\TBAUBIOR.DLL
or c:\windows\system\TBAUBIOR.DLL

if the .dll is on the game cd simply copy it to where it goes.
if not on the cd try finding a download of the .dll

there is a site i think its www.downloaddlls.com
if not it it something close to that.

once you download the .dll
RUN A VIRUS SCAN ON THE FILE!!!
i can not stress that point enough
lastly place file where it belongs and run game
