I'm having trouble with the car keys. I can´t make them stay selected so I can´t use them. What should I do?

You're in the right place to post for the key car, Pmora

How do you try to use this key ? Try to grab and drag them ? If yes, it's not the good way ti use an item : You select it in your luggage (one clic), it appears on the left, at the top.
And then, you click at the place you think it's the good one to use this key and... that's all !

If it solve your problem, I'm afraid you didn't read the "instructions" drawer and worse, the "Download" drawer (on the website).
If not, just explain exactly what you do, what occure.

When I make one click it just zoom them. I get to select it once but only the square stays in the same place where the key is in the bag but it doesnt show the key and of course it doesnt work when I try to start the car. Its like there was a bug or something.

I'm afraid you have a bug, yes. It's the only bug of Amertis, and by chance you had it at the beginning!
Actually, you didn't respect this rule : you must wait 2 seconds, when you take a first object, before taking a second one.

If that happens again, the only solution is to quit the game, and to restart from your last save.
Please, read the instructions of the game (press the space bar, then choose "instructions") not to have this bug again.

Oups, Razibus is right ! It must be the fatal inventory bug !

And I think I was right too when I said that you didn't read carefully the Instructions before begin the game, Pmora

upss, I started with the wrong foot... Yes, I read it, but my english its not good enough I guess. Thank you very much for your help. You 2 are very kind.
see you later. xoxo

No problem, pmora, we really like to help, especially since there's not yet such a crowd on this english forum, so our few current customers get special treatment! See, three of us are focusing on you!

Where are you from, Pmora ? Perhaps we can help you in your language

I'm from Argentina. I speak spanish and english but its a bit rusty since I dont use it too much. my vocabulary its not great. but I was a big fun of Atlantzone and was expecting another round of big fun!! and it was such a surprise when I received the email that the game was back.
And my language wont be a rock in my way to play!!!
I really appreciate your help!

I don't, but maybe Grelot speaks spanish ? We'll know after dinner !

No sabes la alegria que me da esta noticia!!!! Its good to know that somenoe speaks spanish, so I can ask, in case I dont understand something. I'll keep speaking english so the others can get the answers too, and in spanish if I really need it.
