Cookie key problem - move presta to other server

[Flashdancer]

Hy.

Well, sorry my wrong english.

My problem is next: i moved my prestashop the first server on to ohert server.
I copy my full data, and pasted the new server. I wrote config/settings.php file with the new data. My shop working is great, but if would like go to admin, i can't open the page. Only one browser can open that: windows explorer on my pc. Oher browser of computer can't open admin, i get a white page.

I think that, i must write the cookie key, but i don't now.

Thanks for the help, and sorry more one my wrong english.
