IS there anybody who managed to set up a MultiSite in WP 3.6?

Anybody who have succeded? I have installed plenty of Multisites. Maybe I failed with plugins and extras but never EVER have I experienced it a mission impossible even to install the MS.

When using subdomains my WP says "cannot do cause your wild card DNS settings are not correct" after the 8!! try and deletion (and completely washed out the folders)I caved in and went for folders and that is all good until the crucial moment I'm supposed to log in to my multisite and it's does not let me in. Getting freakin' irritated after one day of this ---- so does anybody here have a clue what's cooking with the WP3.6 MS?
