Seems ViTALiTY have released Mass Effect too. This is the third release, the others are here. I recommend you grab the ViTALiTY crack, due to all this business with bad cracks and glitchy games. If you already have the RELOADED or DETONATiON release, then I strongly suggest you obtain this crack. I am really enjoying this game. If you are too, it might be a good idea to buy it, with all of the downloadable content and all – that makes the legit copy (you do not need a crack, for one). Enjoy.
Update: This crack does not fix the overheating-weapon issue. So, I am going to point you into the direction of the iND crack. It has been working fine for me.
