Did you two check your settings to be sure that Persistant Profiles is set to on?
You could post a log file and see if someone here can spot the problem.

This is where the game is failing to load up your profile
I tried to recreate it on my computer (using the same map as you) but everything loads up fine. Can you go in your Saves folder and look in the players.xml file (Drive/Users/Username/AppData/Roaming/7DaysToDie/Saves/Nazegame/Stable)?
Does it look like this (this is the game I just started)? Also, have you started a new game and the issue still exists (not continue on with an existing game)? Your issue might be a corrupted save file. And if so, the next question is does it occur every time you start up a new game.

GamePref.PlayerName =Lord_Bucket_Head
In previous builds there have been reports that non ascii characters in a name will screw up a game or server. You could test that hypothesis with a short/simple name like "Mike" for example.
