Hello Krish, Its due to the fact that the RS232 USB converter and USB blaster uses same resources. Please remove your RS232 USB converter from your system. Reinstall the USB Blaster driver, restart your system and then try to connect to the board. It should work. Please hook your USB serial port to another PC to have communication to your board. If you use RS232 converter and USB blaster from the same PC it won't work. You can verify this by looking at your controlpanel-> system -> hardware-> device manager. If the usb blaster is connected properly you should see the altera usb blaster here. Else you wont see or you see with warning sign. In this case you have reinstall the usb blaster after removing the RS232 usb converter. All the best.
