Well, I had one probleme where I had a similar, or maybe the same, who knows? What I did is of course uninstall everything, if you have trouble, do a search for bitcomet. And then get the 1,06ver of bitcomet the 1,10ver is twichy right now.
And when installing it change the install directory to bitcomet2
It solved almost everything.
Good luck!
!Hasta luego!
