Courtesy of pcultimate from the Bioware forums for creating the dummy load.blk files and mtvnot from Piratebay for figuring out the fucked up .blk files that don't play correctly for whatever reason:
Get those files.
Replace the following files ONLY, NOT ALL OF THEM
, or you won't be able to move forward with the game past the IFF sequence of events. Only the files below are broken, the rest you should be able to watch.
If you're getting in-game freezing every few seconds, do the following:
Go to the folder where you installed the game.
Go to Binaries and make a shortcut of MassEffect2.exe.
Now open properties on this shortcut and add the line -nomoviestartup.
It should look like this "...Binaries\MassEffect2.exe" -nomoviestartup.
Start the game. It should work lag free now.
