Monodevelop Unity 4.0.1: "An Error Has Occurred"

Ever since downloading Unity 5.3.1f1 Personal, Monodevelop Unity (currently version 4.0.1) has been popping up an error window about every 5 seconds or sometimes when I save a script. It has been really annoying to program anything with a window constantly popping up. It says this:

"An error has occured
Details of this error have been automatically sent to Xamarin for analysis.

Hello,

You can try to re install mono develop, it seems there a version issue.

 

Yeah. Do you know the link to download the latest version of MonoDevelop-Unity?

 

http://www.monodevelop.com/download/

 

Does this work with Unity? Because the application itself that I have is called "Monodevelop-Unity". This is just for Monodevelop.

 

Sorry, i guess i answered too fast. To be honest i thought monodevelop was a Unity solution only. Seems i was wrong.
Clean reinstall of Unity should solve the issue. You can also check this thread, look like the guy use the monodevelop version.

 

Ok Thanks.
