Males can't access Femals Fourm

[inshad]

HI,
I wrote a hook with VB3.5.1 that allow only females gender to access a certain forum (Which was for the ladies only).
and it's working fine.

but when I upgrade the forum to the version 3.5.4 , it's not working, and Males can access the forum normaly !

Would you please assist me on that ?
