OMG, just after i gaveup and made the post. i got it working at last.

here how i did it.

on the working PC i notice my ".frostwire" folder is in the user root folder.

but the not working pc the folder is in the user/application data folder as "frostwire"

i deleted it and copy from the working pc and place it in the user root folder.

now everything works.

must be something wrong with my installer..
