Help for unknown protector

Unpacked file here http://www.multiupload.com/I3989AR3HX
Two api calls left unidentified
0046A918 . FF15 6C40BC00 CALL DWORD PTR DS:[BC406C]
0046AB1C . FF15 6840BC00 CALL DWORD PTR DS:[BC4068]
They don't look like regular API calls so I just nopped them.
Overlay also exists but wasn't appended to minimize the size.
Last sections were cut and resources were rebuilt.
The file seems to be working fine on 2 different OSs but I haven't tested it thoroughly.
It's just unpacked, nothing else is patched or cracked.
