AVRdude: stk500_getsync(): not in sync: resp=0x00

I'm trying to flash the firmware onto a generic Multiwii SE and I'm having one problem after another. I ordered an FTDI first but it was bad. So after a week of trying to get the PC to recognize it I finally sent it back and ordered a cp2102 UART till my replacement comes. I downloaded and installed the drivers from Silabs and the computer does recognize the Cp2102 but when I try to upload to the Multiwii I get the message listed above in the subject.

I have looked at solutions but really don't understand what I'm doing. Can someone help me figure this out please.

Did you have an Arduino-related question?
