Connectivity issues

I have sanguinololu 1.3 and I am trying to run the sample Blink LED program. But getting the following errors.

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

My configuration is:
Windows 7 64 bit and I have tried running the program with the same error on Arduino version 22 and 1.0.3

We have followed instructions of copying the sanguino directory under hardware folder. Any help is greatly appreciated.

Thanks Regards
