1. Is WotLk installed? Must have WotLk for it to work.
2. The name of the patch must look like this: patch-X.MPQ
Make sure "X.MPQ" are capital letters, and "patch" not capital.
3. If you have another custom patches in this folder, try to move them to another folder (so they are disabled) and try again.
I just tried it with both of the files and only one of them worked. Seems like you can't get both of them to work at the same time, since one overwrites the other.

I'll try to make a single patch with both of them and see if it works.
Ok, both in a single patch working:
NeF and NeM -> Alex
