4. Right click on the MassEffect_PinnacleStation.exe and open it with 7-Zip
5. Extract the folder Outdir to your desktop, you see 2 folders are located there Biogame and DLC.
6. Copy the Biogame and DLC folder to your mass effect folder (where you installed it) (D:Program Files (x86)Mass Effect). If it asks to overwrite say ''yes to all''
7. We are almost done, when you load the game and check if the dlc is installed correctly it shows up the Bring down the sky only.....this is because the DLC miss a file (don't ask me how or why).
8. Download this file
9. Open it with winrar and you see 1 folder with 2 files, use the reg file to add the serial key in the registery (this because when you try to install it from cd it fails).
10. Copy the AutoLoad.ini in the DLC -> DLC Vegas folder, this will unlock Pinnacle station in the menu.
PS: Use the Skidrow crack (version 1.02), because reloaded does not seem to work with the DLC's
