Script does not remove MSET9

Hi all!

In the past I had already successfully modded my old 3ds XL. Now I have a New 3ds XL and I decided to mod that as well.

The Super-skaterhax didn't work for me, so I used MSET9 instead. Everything worked perfectly, right up to step 6. from Section IV - Removing MSET9.

I successfully removed the trigger file in step 5., but when type 5 to remove MSET9 I get a FileNotFoundError and the script stops.

The only help I find online is to manually remove the Nintendo 3DS folder, but I only have one source for that.

How do I successfully remove MSET9, so I can continue the guide?

Thanks!
