WL7 run slow on Win8 64-bit

I had e-licenser v 6.5.4.1115, and after upgade to 6.5.4.1117 ot seem to be ok!
This evening I tested all combination of sample rates. Problem persist only in situation when I close Cubase 7 and start running WL 7, but not every time, especialy when the Cubase project have different sample rate than Wavelab.
Thanks!
