KB Crossworlds Loading Problems

[Zepdog]

I have played King's Bounty Crossworlds for around a year. A couple of weeks ago I had a problem with the game not booting up (even the original). This was most likely due to a malware I erased that shared a file. I deleted the game and reinstalled then it wouldn't accept the cd key. So I did it again and only loaded the Original KB Armored Princess. I finally got that to work. Now when I try to load the Crossworlds dlc it can't find the original games' folder. It gives the 1c publishing folder as the default but when I click it it says that it can't find the original game on my computer and to maually direct it to the file that the original Armored Princess is. When I do that I just keep getting the same pop-up that it can't find the game. So with this I can't install the Crossworlds version now. Any help would be appreciated. Thanks.
