Tell me which download and were u get it from and i will try and help u

same thing happened to me! i got the downloads on Zoo Tech Pheonix or something like that.

I tried to download house cats and unicorns, but it didn't work. I think it's because the
game doesn't recongnise the download coding.

Have you cheacked the disk on what brand of computer. on the back look for system
requirements.And see weather your computer is XP or Vista. coz a game could be on vista
and your computer might be XP... Some games can go on both but only say's like XP it's a
bit annoying realy.

there not working because it is usermade downloads don't work unless you have the right
expansin pack

I have made downloads from Zootycoon UNLEASHED, but I can't get them working. Help,
please?!
Look, I've tried copying the files into the game, and also, I've seen that the
requirements are met. I've downloaded the unicorns, the Umbreon, and the albino lions
along with domestic cat.
Also, I have the whole pack of ZT2, except for Marine Mania, and Dinosaur Digs!

I want the Unicorn for ZT2 badly. Wait.. I thought that Umbreon is from Pokemon !
