Fletching Auth Problems

Ok, so I have the fletching auth, and I have been using it with no problems.

Today I got 90 fletch and of coruse i started fletching Magic longbows, but for some reason it won't work with the magic longsbows. It did Yew longs, and Magic shortbows flawless but it won't do the magic longs.

When I tell it do it all it does it click in between the make longbow and shortbow option and then banks the logs. It is very annoying.

What is wrong? And what do I do?

 

Autofletcher, Perfect fletcher or free script?

 

Idk what it is called. I bought it from Autofighter.org and its a fletch auth.
