1.5.2 won't find new hardware profile

i have a freetronics leostick hardware profile and want to use it with the 1.5.2 ide but when i put the profile in the hardware folder it won't show up in the software am i doing somehting wrong?

Leostick is supported by Freetronics, you should ask them.

I don't see a good reason to 1.5.2 for a Leonardo-based board. 1.5.2 is really targeted for the Due at this point.
