Yes, I have portable version and I can see QaConfig.dat there. Maybe it works. ;P
Edit:
Yesssssss, it worked buuuuuuuuuuut, then it's back to new QA. :@
I don't touch anything, I see my old then after 1-2 seconds QA is refreshed itself and removed my favorites. I understood, it synced QA but why?
I will sign out then sign in again. Or any idea?
Edit 2: signing out and resign in didn't work then I tried to sync fast but it's impossible then I had good idea, I disabled sync of QA and now my favorites from QA are back hehehe.
But... what happens if I reenable sync QA? I tried it. I reenebaled it, synced and back to unsaved QA favorites. I don't know what to do now. ;P Fow now I keep unsynced QA data until you give me another idea.
