IDE 1.6.4 AVSIRP MK II

I upgraded to 1.6.4 IDE and my ATMEL AVRISP MKII will no longer function..
created new device with inf-wizard.. did not resolve issue..

Does the MKII no long function with 1.6.4 worked flawlessly prior to upgrade.. still operates as well on 2nd PC running IDE 1.0.5 r2

1.6.4 works good
