Monodevelop autocomplete problem [SOLVED]

Hello, I have a problem with monodevelop, I do not see the autocomplete box correctly, only some minimal information appears.

How can i fix this?.

In this gif you can see that when I type the name of the variable “cadena.” Of type String, the methods of this object do not appear in the autocomplete box.

Here are the options I have activated in Monodevelop:

I have the latest version of Unity (5.5.2f1) and Monodevelop (5.9.6).
Thanks and sorry for my english.

SOLUTION: ACTIVATE THIS WITH WINDOWS UPDATE ACTIVATED

Thank you!

I followed all of the above , tried reinstalling 3.5 , 4.7.1 and 4.7.2 - I get some odd errors in the background saying something in the microsoft code/references is out of date since installing the latest version of Unity.

Will see if reinstalling an older version of Unity will fix it.
