Problem burning hex file to 89V51RD2, is there an alternative to Flash Magic?

I use Flash Magic for programming my 89V51RD2 and have had no problems with it prior to today. Since this morning (12Hrs ago) Iv been trying to burn a hex file to MCU with no look, I keep getting the error "Unable to connect at specified baud rate..." Iv tried different baud rates but it hasn't made any difference.

The only other thing I can think to do is to try another programmer application, but I cant seem to find any alternative.

Any alternative will need to be Windows 7 x64 compatible.

Thanks
