Hi Holger1405
thx for your reply
In the meantime i have refunded the game at origin and bought it at steam (2 GBP more). The download and installation was no problem but I couldn't start it via steam. I also could not redeem the cd-key in origin. So i downloaded the two addon from EA,-> installed both -> made a desktop shortcut to the masseffect.exe in the binarys folder. Then I managed somehow to tell my system to run this in xp (sp2) compability mode and as administrator and voila everything went smooth.
I hope I will be able to transfer my savegame from the steam Mass Effect 1 to origin Mass Effect 2.
As for the Origin store. I think this is a total mess. I bought ME 3 and an upgrade to the deluxe edition (as this was a few pounds cheaper than buying the deluxe editon on its own) while I was still having access. Now it shows me a standard ME 3 which i own and a deluxe ME3 which I can play again via subscription renewal or purchase. Very confusing. I think I have all the content of the deluxe edetion as I could find the pdf-files of it.
I still couldn´t find a way to find out if the addon of the dlx ed is also playable. (as I still dont know how to play them at all in all Mass Effect titles) I am still a newvie to the game.
