Nokia Nseries :: Ovi Won't Import .vcf Contacts Files To N8?

im finally have N8, and when i tried to export my contacts file witch is .vcf out of my old nokia 7610 to transfer it to my new N8, the PC Suite wouldn't work with N8, so i downloaded Ovi Suite and its worked fine with N8, but the big problem that when i tried to transfer the contacts files using Ove Suite i found that its must be ends with .nbu extension to be restored and while n8 doesnt work with pc suite, what can do to restore my contacts, help me cuz i feel dead without my contacts file |- i forgot to tell you that i can't copy it on my SIM card then copy it again to my N8 and repeat it till done, i have little problem with the option button with my old phone Nokia 7610
