SDL Language Cloud - Object reference not set to an instance of an object

Question

Hi, 
 I have an unusual problem with SDL Language Cloud. When I want to select it from the list of TM or AT providers, within Project settings, I get the following error: "Object reference not set to an instance of an object". Is there something I am not doing wright or this is some "background" technical issue? I use Free Subscription, I am able to log in to SDL Language Cloud within my Trados Studio 2015. 
 Thanks!

Hello Igor, 
 
I think it makes sense to try a Studio reset to resolve this. Rename this folder (just add _old to the end or something, it's not important what you rename it to) and restart Studio: 
 
c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\12.0.0.0 
 
See if that helps.
