[NewGen WE] Win32 application?!

[~GaLs~]

I am using the latest newgen WE, v5a.

After using it, I found out that I can't open my maps by double-clicking again.
When I'm using v4x, I can double and open my map with Newgen, but currently can't with an error message displayed.

The error messages write C:\Documents and Settings\admin\Desktop\NewMap.w3x is not a valid Win32 application.

You need to re-register the file extension because the path of the editor changed.
Do this by
1) Deactivating Extensions\Register Shell Extensions
2) Re-activating it -> then it associates it to the new editor
