I can't open any file anymore. Studio 2011. Error "Value cannot be null. Parameter name: value"

Question

Hi Everyone!

I was working on a project when I took a break, and when I came back to Trados, the MyMemoryPlugin didn't display anything anymore, so I restarted Studio.

But then,I could not open the file I was working on, or any other file.

I've received the error message: "Value cannot be null. Parameter name: value"

Here's what the error report looks like, don't know if that helps:

<StackTrace><![CDATA[

Any help?

Hi Fr&eacute;d&eacute;ric, 
 This error message referring to Newtonsoft.Json is a message we used to see from time to time because MyMemory used a conflicting version of this file to Studio. But it is odd it just happened. I think the best solution might be to try a Studio reset. 
 This article explains what to do: 
 Studio reset: 
 But only apply the first two as you don't need to change the projects folder for this problem: 
 C:\Users\[User_Name]\AppData\Local\SDL : delete/rename the SDL Trados Studio and ProjectApi folder 
 C:\Users\[User_Name]\AppData\Roaming\SDL : delete/rename the SDL Trados Studio folder 
 Don&rsquo;t do number 3. ie, the projects folder.
