Ihave an avatar and i have two folders of essesntials for it, one male one female. lately the female skin has shifted to male. i tried buying the skin again but same thing happened.

I'm not quite clear about what's "shifting" here.  Your skin is a texture that's applied to your avatar.  If your male skin has a mustache and chest hair, it can't suddenly develop pouty lips and a cute beauty mark instead.  That's not the way textures work.  You might have a problem with your male and female shapes, but that's a different matter.  A male skin on a female shape can make you look like the bearded lady, but it's not the skin's fault. 

If you seem to be loading a female shape accidentally, that's a version of a bake fail.  You can usually solve it with the solutions here >>> http://wiki.phoenixviewer.com/doku.php?id=fs_bake_fail . Start with the simple things at the top of the list and work down until you find what works for you today.
