Win8 problem

after install Fusion asks on first run serial again, when entered, it says,
"we're sorry.. Please make sure that software is installed correcly"
after clicking "ok" it says:
"MixMeister was unable to save your playlist. Please try saving again to a diffrent location" after "ok" it shuts down.. What playlist? i just installed the software...

i've seen that there was Fix for MAC, but is there for Win8?
i didn't find place called /library/preferences in Win8

Any idea?
