Commented Issue: Error loading the ResX Manager extension [4736]

The extension crashes as soon as you open it from the Tools menu. The error message states to look in the Output window, below is the next from that window. It used to work but now no longer does, I am not sure what changed. Visual Studio usually crashes shortly here after. This is a shame because I really like this extension.

Software Specs (everything is patched to latest as of 2016/07/07):
* Windows 10 64bit
* Visual Studio 2015 Enterprise
* Resharper plugin

From the Output window

```
