Hello Everybody, 
I have an EwE 6.6.16540.0 in my computer works on x64 (and also EwE is same). 
When I try to plot MTI, its gives that error;
- And you can find an error log attached. 
After the choose Continue it gives only red cross lines (nothing). 
I tried same model files in different computers (three different windows).
When I tried old version of EwE which is 6.5 (it opens via read only mode) it works for only read it. 
I google it this error '' System.NullReferenceException: Object reference not set to an instance of an object. ' but it is so general error name. They didnt work to solve this error.  
And also this error continue with every new models. 
I can not deal with this problem, but I know that solution is so easy peasy for developers.
Best regars 
Alain.
