How to contact 4j studios?

How can I contact 4j studios? I think the only way to fix this is for them to tell me how. This isn't just a regular bug in minecraft. Basically the problem is, I just got minecraft pc and I started off just playing vanilla then I wanted to install some mods (first time ever using them) I installed kovacics mod pack and when I went on to minecraft there were no mobs whatsoever in the world. No hostile mobs or animals. I created multiple new worlds, looked around for ages ad still no animals. I deleted all the mods and the kovacics mod pack and tried installing mods on there own(without a mod pack) I deleted the kovacics profile on minecraft and got a new forge one and downloaded the mod mo creatures. For some reason it wasn't coming up with mo creatures in the mods list in the game and I had installed it correctly and done everything. So anyway I created a new world anyway ad there's still no mobs and animals anywhere. When I pres escape and go to statistics the mobs button is grey and I can't press it. When I go to mod options it says test 1 test 2 disabled in red. What does that mean? The only way I can get mobs is if I spawn them in myself on creative mode or with too many items mod(which I did have installed with kovacics mod pack) the only mobs that are spawning is villagers. So basically everything was working fine them when I installed mods there were no animals or hostile mobs. There are still animals on my vanilla world tho.

First of all. 4j is responsible for updating, making and bug fixing the console versions of Minecraft. You'll need to contact Moment somehow but your better off going on a Minecraft help forum where many experienced Minecraft players and modders can hero you BUT wait! These might be the reasons Minecraft mobs won't work…

You might have a free older version of Minecraft where mobs haven't yet been programmed to work with the game.

You might have a free cracked version which will you will need the hacker/cracker/modder to fix your problem because he or she might have made a programming mistake.

You might actually not have "Minecraft" but since other stupid fakey.

Either way. Ask 3 above Mojang can't help with unless you bought and downloaded the game if the www.Minecraft.net website. Then they can help.

Your better off looking for they're email on the website or they might have some sort of customer service phone line. You'll need to check they're company website out Minecraft.net
