Recently I changed my Windows from Win 7 32 at Win 7 64. After this,I download the game again from steam but surprise: don't work.I mean,when I run the game,i need to wait maybe 5 minutes,after this i receive an error with: you have 11 evaluation day,after this bla bla bla(or something like that). I click ok and,surprise again:unknown code. On Win 7 32 worked very very good.I mean,I had the same patch(new Sam megapatch(2016) ) installed on the game and I don't receive any error.Can someone explain me what's and why happened this? Thanks a lot!
