ME1 savegame Corruption

Hi guys!

I played ME1 long ago on PC with a cracked and localized (HUN) version of the game. Back than, I even managed to install Pinnacle Station DLC by manually rewriting localization in some of the .ini files. So I played it through 3 times and have a lvl. 60 character.

Now I bought the game on Origin, and this one is international version, which I don't mind, but it doesn't load my old savegames. I can start new game, and it lists the DLC-s in the menu as well, but I cannot load either of my saves as it says: "Downloadable content is missing. Modules is question: Zúgjon az ég!" - which is Bring down the sky with localization.

I tried installing the localized version (downoaded again from torrent), and install DLC-s separately. In this case it says "Modules in question: Pinnacle Station". - even though it is intalled with the same trick I did before.

I believe I pretty messed up the localization of my original save files. Is there anything I can do, to use these saves again? Anyone, any idea how to change the localization of the save files?

Thanks for your help!

(BTW: I'm using Win8.1 x64, but everything tied to ME runs in XP SP2 compatibility, with admin rights, even Origin itself)
