Lost NC Icons

Hi, Sherry!

Thanks for giving me a new pw! Now I can communicate in the Forum.

Here is my problems.
1. I upgraded my NotComp a few months ago and lost file icons:

Now it looks like 'unknown file's type'. Double click open it as NotCom, though...

2. From the very beginning I associated midi with NC:

...but it opens with any software, but Notation Composer!
So, I have to make right click on midi icon and then choose NC from a drop list.
Sometimes it's very annoying...
