And not able to see ur USB BLaster in Programmer window.....if you are sure that nothing is wrong with driver(signed driver),and u are able to connect your pc with other USB Blaster, i mean try out if its possible with the other similar board(may be of frnd) if programmer window detects it...then the only problem is ....(this was my case) When u plug in USB Blaster this blaster assigns an serial id to the device on board(eeprom)....you need to change this serial id...you can reprogram this by using the utility MProg from FTDI...u need .ept file .... create an .ept(sampe.ept)d file by copying the below content....
