Problems with Custom Installer 2010

Hi.
I downloaded and installed the MTG Custom installer 2010, everything went fine. Installed to default path with short name, copied New card arts (and lowered sounds 'cause they were annoying in previous versions so I deleted them :p).
Anyways, I made deck with all the new shiny cards and was able to get into duel. My deck had Polluted Delta, which I played and tried to tutor for land cards. Game froze. Game just waited and waited (mouse changed to waiting icon). I could preview cards on the field etc. but nothing just happened. It felt like AI didn't know how to handle the card and just started think what to do.
I ran few tests after that, by making a deck with 38 Polluted deltas, 1 swamp and island. Me and AI had those decks. AI goes first and game froze immediately in his main phase. wtf? Same things happened with every other Land-Tutoring-Lands.
Ok, so that was problem #1. Second one is that I downloaded somebody's deck on the forums, which I couldn't play because I didn't have all the cards, but in the deckeditor there were cards that weren't normally in deck editor. Like 1 card was kobold legend and it gave all kobolds +2/+2 or something like that. My editor doesn't have card like that but it was still there.
I have no idea what I have done wrong here, and I thought this should be easy enough. :/ Im running Windows 7 Ultimate 64-bit.
TL:DR. Polluted Delta doesn't work, weird cards in deck which aren't in editor, W7 Ultimate 64-bit.
