Resolved Can just play 32bit version and mod-less

First of all I play Starbound through Steam.

A few days ago Starbound starts to show me a message when I want to play it, saying following:
Steam could not synchronize your files for Starbound with SteamCloud and when I continue I will lost the files. But I have never played Starbound somewhere else. Just on my PC. So I didn´t thought about it and Start the game without any other Problems.

I installed a few Mods and they all worked perfectly. A few from Steam, a few form here. No Problems.

Yesterday when I started Starbound it crashed. The Fish appeared, and then black. So I tried it again with the same result. I started my Steam again. Same result. I started my PC again. Same result. There also appeared a message everytime it crashed, but I don´t understand what its saying:



Then I tried to run Starbound via files. I get in the folder where Steam is installed, steamapps, common, Starbound, win64 and then I tried to start .exe. It worked, but just the 32bit version and all my mods where gone.
So I tried it with my Backups; it worked for Steam but it is still the 32 bit, mod-less version.
I also uninstalled Starbound and installed it again, but nothing changed.
Oh, and I also uninstalled every mod on Steam and in the mod file, I thought maybe the Problem is an defect Mod..

So in short the Problem is:

• I can just play the 32bit version
  
• and mods are not working anymore

I never had any Problems with Steam or Starbound befor, so I beg you for some help, please. I love Starbound. :'(

 

Hurray I fixed it!!! Q7Q

For everybody who had the same problem: I guess it was a defect Mod, but I dont know which one.

Solution:
Steam - steamapps - common - Starbound - storage
Copy the Player and Universe folder and save them somewhere else in a Backup folder
Delete everything from storage
Copy and paste the Player and Universe folder from your Backup folder to the storage folder
For me it worked; I can play the 64bit again and my mods are working *-*
