Necessary to Start a New Game?

[Watchsmart]

I am currently in the middle of a Baldur's Gate 1 game.  I haven't started Siege of Dragonspear. 

Is it safe to install the Enhanced Edition Trilogy mod and continue my game?  Or should I start a new game?

Thanks!

Unless you know exactly what you're doing and the modification is fairly minor, (un)installing mods on a running game is never safe.  And you actually can't install EET on a BG1 game, it installs on BG2 and pulls the resources from BG1 in.  Your BG1 save will likely not work with it at all.
