Out of the sudden i'm getting this error " Unable to open Apex Code Editor Reason null argument" using my eclipse tool, last time I worked in my eclipse project was Monday and everything was working fine.

I'm using Eclipse Neon.2 with Java 8 Update 121 (64-bit) and Java SE Development kit 8 Update 121(61-bit) in a surface pro 4 with windows 10 as an operating system.

I have uninstall/intall the Java Kit and Eclipse three times and i keep getting the same error while triying to create a new trigger.  I had read and tried everything from prior post in this isssue but nothing have worked so far for me.  

Any help!!!!
